DOW Chemical CO. – New Research may Enhance Display and LED Lighting Technology: More Efficient – Lower Cost Quantum Dots


U of Illinois QD 150807131233_1_540x360Large-area integration of quantum dots, photonic crystals produce brighter and more efficient light.

Recently, quantum dots (QDs)–nano-sized semiconductor particles that produce bright, sharp, color light–have moved from the research lab into commercial products like high-end TVs, e-readers, laptops, and even some LED lighting. However, QDs are expensive to make so there’s a push to improve their performance and efficiency, while lowering their fabrication costs.

Researchers from the University of Illinois at Urbana-Champaign have produced some promising results toward that goal, developing a new method to extract more efficient and polarized light from quantum dots (QDs) over a large-scale area. Their method, which combines QD and photonic crystal technology, could lead to brighter and more efficient mobile phone, tablet, and computer displays, as well as enhanced LED lighting.

With funding from the Dow Chemical Company, the research team, led by Electrical & Computer Engineering (ECE) Professor Brian Cunningham, Chemistry Professor Ralph Nuzzo, and Mechanical Science & Engineering Professor Andrew Alleyne, embedded QDs in novel polymer materials that retain strong quantum efficiency. They then used electrohydrodynamic jet (e-jet) printing technology to precisely print the QD-embedded polymers onto photonic crystal structures. This precision eliminates wasted QDs, which are expensive to make.

These photonic crystals limit the direction that the QD-generated light is emitted, meaning they produce polarized light, which is more intense than normal QD light output.

According to Gloria See, an ECE graduate student and lead author of the research reported in Applied Physics Letters, their replica molded photonic crystals could someday lead to brighter, less expensive, and more efficient displays. “Since screens consume large amounts of energy in devices like laptops, phones, and tablets, our approach could have a huge impact on energy consumption and battery life,” she noted.

“If you start with polarized light, then you double your optical efficiency,” See explained. “If you put the photonic-crystal-enhanced quantum dot into a device like a phone or computer, then the battery will last much longer because the display would only draw half as much power as conventional displays.”

To demonstrate the technology, See fabricated a novel 1mm device (aka Robot Man) made of yellow photonic-crystal-enhanced QDs. The device is made of thousands of quantum dots, each measuring about six nanometers.

“We made a tiny device, but the process can easily be scaled up to large flexible plastic sheets,” See said. “We make one expensive ‘master’ molding template that must be designed very precisely, but we can use the template to produce thousands of replicas very quickly and cheaply.”

Quantum Dots are ‘Ready for Prime Time’ says Analysts, Yole Development


Yole Développement says revenues “will exceed phosphors by 2020” as adoption into LCD TVs rivals OLED quality.

QD Prime Time YoleQDotsM

Quantum dots’ virtual adoption cycle, according to Yole Développement

Yole Développement (Yole), the Lyon, France-based market research and strategic

consulting company, has published its new LED down converters technology and market

report, entitled Phosphors & Quantum Dots 2015: LED Down Converters for Lighting & Displays.

It presents a detailed review of the industry, especially the impact of the development of

quantum dots on the display and conventional phosphors industry. Yole asks, are quantum dots

now a serious competitor to OLED-based technologies – and its conclusion is: quantum dots

are finally ready for prime time and will exceed traditional phosphor revenue by 2020 by

allowing LCD to compete with OLED in the race for the next generation of displays.”

After the lukewarm reception of 3D and 4K screens, Yole comments that the display

industry needs a “new and disruptive experience improvement” to bring consumers back

to the stores: “image quality perception increases significantly when color gamut and

dynamic contrast ratio are improved.” Yole also notes that “Leading movie studios,

content providers, distributors and display makers have together formed the UHD Alliance

to promote those features.”

Dr Eric Virey, Senior Analyst, LEDs at Yole, commented, “OLED was believed to be

the technology of choice for this next generation of displays. But production challenges

have delayed the availability of affordable OLED TVs. LCD TVs with LED backlights

based on quantum dot down-converters can deliver performance close to, or even

better than OLED in some respects, and at a lower cost.”

 

QD-LCD ‘could pull ahead’ of OLED display

Until OLEDs are ready, says Yole, “QD-LCD technology will have a unique window of

opportunity to try to close enough of the performance gap such that the majority of

consumers will not be able to perceive the difference between the two technologies

so price would become the driving factor in the purchasing decision.” Under this scenario,

the analyst believes that QD-LCD could establish itself as the dominant technology while

struggling OLEDs “would be cornered into the high end of the market.”

Yole acknowledges that OLED-based displays potentially offer more opportunities for

differentiation but the analyst notes, “OLED proponents need to invest massively and

still have to resolve manufacturing yield issues. For tier-2 LCD panel makers who

cannot invest in OLED, Quantum Dots offer an opportunity to boost LCD performance

without imposing additional CAPEX on their fabs.” At this year’s Consumer Electronics

show, as optics.org reported, no fewer than seven leading TV OEMs including

Samsung and LG demonstrated QD-LCD TVs.

 

With tunable and narrowband emissions, QDs offer design flexibility to developers

of new displays. But more is needed to enable massive adoption, including the d

evelopment of cadmium-free formulations. Cole cautions that “traditional phosphors

still have to say their last word”. If PFS could further improve in term of stability and decay

time and a narrow-band green composition was to emerge, traditional phosphors could

also be part of the battle against OLED, Yole concludes.

Yole’s analysis Phosphors & Quantum Dots 2015: LED Down-converters for Lighting & Displays

presents an overview of the quantum dot LED market for display and lighting applications

including quantum dot manufacturing, benefits and drawbacks, quantum dots LCD versus

OLED and detailed market forecast. For more information about this report and other

2015 Quantum Dot display buzz continues with announcements from TCL, AUO and Tianma NLT


Quantum Dots continue to be one of the hottest trends in the display industry. Following the buzz from CES 2015 in Las Vegas a number of exciting new Quantum Dot displays are now hitting the market from top set makers. Here’s a roundup of the latest news:TCL QDTV featuring Quantum Dot Enhancement Film on display at a launch event in China

Nanosys 1 -423 1429654580386

TCL, the world’s 3rd largest TV brand, just launched a new range of curved, Ultra HD Quantum Dot TVs, called the H8800S series. According to TCL, the new sets “adopt quantum dot color enhancement materials and a curved display to achieve an unparalleled color gamut coverage of 110% NTSC for curved TVs.”

Taiwanese display panel maker AUO also announced a full line-up of Quantum Dot displays ranging from 55″ to 85″ at the CITE show in Shenzhen, China. Dubbed “ALCD” for Advanced-LCD, the sets all feature UHD resolution, HDR with direct LED backlighting and Quantum Dot wide color gamut. The 65″ model also comes in AUO’s favorite 3000R curvature for a more immersive experience. All models are expected to ship during the second half of 2015.

Bringing better pixels to UHD with Quantum Dots
The next wave of market push for TVs is Ultra-High Definition. The increase in resolution from HD to 4K is perhaps the most well known benefit of UHD but there is much more to this new broadcast specification. High dynamic range (HDR) and wide color gamut bring more perceptible benefits to users in terms of an improved viewing experience than improved resolution alone. The ultra-high color gamut standard Rec. 2020 was originally defined for laser-based projectors where the color primaries are on the color locus of the CIE diagram. Because of the deeply saturated color coordinates, Rec. 2020 is beyond the capabilities of OLEDs. Is the Rec. 2020 color standard reachable for consumer displays or is it only for high-end laser-based projection systems? This presentation explores the capability of using quantum dots in LCDs to reach the ultra-high color gamut of Rec. 2020.

High-Efficiency, Low Turn-on Voltage Blue-Violet Quantum-Dot-Based Light-Emitting Diodes


ACS QD LEDs nl-2014-04328f_0007We report high-efficiency blue-violet quantum-dot-based light-emitting diodes (QD-LEDs) by using high quantum yield ZnCdS/ZnS graded core–shell QDs with proper surface ligands. Replacing the oleic acid ligands on the as-synthesized QDs with shorter 1-octanethiol ligands is found to cause a 2-fold increase in the electron mobility within the QD film.

Such a ligand exchange also results in an even greater increase in hole injection into the QD layer, thus improving the overall charge balance in the LEDs and yielding a 70% increase in quantum efficiency. Using 1-octanethiol capped QDs, we have obtained a maximum luminance (L) of 7600 cd/m2 and a maximum external quantum efficiency (ηEQE) of (10.3 ± 0.9)% (with the highest at 12.2%) for QD-LEDs devices with an electroluminescence peak at 443 nm. Similar quantum efficiencies are also obtained for other blue/violet QD-LEDs with peak emission at 455 and 433 nm. To the best of our knowledge, this is the first report of blue QD-LEDs with ηEQE > 10%. Combined with the low turn-on voltage of ∼2.6 V, these blue-violet ZnCdS/ZnS QD-LEDs show great promise for use in next-generation full-color displays.

Are Quantum Dot TVs – (some with) toxic ingredients – Better for the Environment – Your Health?


QD TV Health id38626Earlier this week, The Conversation reported that, “The future is bright, the future is … quantum dot televisions”. And judging by the buzz coming from this week’s annual Consumer Electronics Show (CES) that’s right – the technology is providing manufacturers with a cheap and efficient way of producing the next generation of brilliant, high-definition TV screens.

But the quantum dots in these displays also use materials and technologies – including engineered nanoparticles and the heavy metal cadmium – that have been a magnet for health and environmental concerns. Will the dazzling pictures this technology allow blind us to new health and environmental challenges, or do their benefits outweigh the potential risks?
Answer’s not black and white
quantum dot display

(click on image to enlarge)

Quantum dots are a product of the emerging field of nanotechnology. They are made of nanometer-sized particles of a semiconducting material – often cadmium selenide. About 2,000 to 20,000 times smaller than the width of a single human hair, they’re designed to absorb light of one color and emit it as another color – to fluoresce. This property makes them particularly well-suited for use in products like tablets and TVs that need bright, white, uniform backlights.

There are of course other chemicals, such as phosphor, that fluoresce and are used in consumer products. What is unique about quantum dots is that the color of the emitted light can be modified by simply changing the size of the quantum dot particles. And because this color-shifting is a physical phenomenon, quantum dots far outperform their chemical counterparts in brightness, color and durability.

Unfortunately, the heavy metal cadmium used in the production of many quantum dots is a health and environmental hazard. Under the European Restrictions on Hazardous Substances directive, its use is restricted in electronic equipment. And cadmium and cadmium compounds have been classified as carcinogenic to humans by the International Agency for Research on Cancer.

On top of this, the potential health and environmental impacts of engineered nanoparticles like quantum dots have been raising concerns with toxicologists and regulators for over a decade now (“The New Toxicology of Sophisticated Materials: Nanotoxicology and Beyond”). Research has shown that the size, shape and surface properties of some particles influence the harm they are capable of causing in humans and the environment; smaller particles are often more toxic than their larger counterparts. That said, this is an area where scientific understanding is still developing.

Together, these factors would suggest caution is warranted in adopting quantum dot technologies. Yet taken in isolation they are misleading.
Quantum dots under glass
The quantum dots currently being used in TVs are firmly embedded in the screens – usually enclosed behind multiple layers of glass and plastic. As a result, the chances of users being exposed to them during normal operation are pretty much nil.
The situation is potentially different during manufacturing, when there is a chance that someone could be inadvertently exposed to these nanoscopic particles. Scenarios like this have led to agencies like the US National Institute for Occupational Safety and Health taking a close look at safety when working with nanoparticles. While the potential risks are not negligible, good working practices are effective at reducing or eliminating potentially harmful exposures.
End-of-life disposal raises additional concerns. While the nanoparticles are likely to remain firmly embedded within a trashed TV’s screen, the toxic materials they contain, including cadmium, could well be released into the environment. Cadmium is certainly a health and environmental issue with poorly regulated e-waste disposal and recycling. However, when appropriate procedures are used, exposures should be negligible.
These concerns could be enough to tip the balance against using quantum dots in consumer electronics for some. But they only tell part of the story because these small, bright particles also come with environmental benefits.

But there are bright benefits
Quantum dot TVs can be upward of 20% more energy efficient than conventional LED TV screens. And because quantum dots are such an efficient source of bright light, the amount of light-emitting material in these screens (as low a milligram of cadmium in some models) may actually reduce the overall amount of toxic materials used.
These energy and material savings translate into reduced environmental and health impacts. But are they enough to justify the use of a potentially toxic material?
The company QD Vision has grappled with precisely this question. In developing quantum dots for products like Sony’s TCL Quantum Dot TV (debuting at CES this year), the company explicitly adopted an approach to responsible development that considered health and environmental impacts. As a result, in 2014 they won the Presidential Green Chemistry Challenge Award from the US Environmental Protection Agency (EPA).

Although it seems counter-intuitive, analysis by the company that was made available to the EPA showed QD Vision’s products lead to a net decrease in environmental cadmium releases compared to conventional TVs. Cadmium is one of the pollutants emitted from coal-fired electrical power plants. Because TVs using the company’s quantum dots use substantially less power than their non-quantum counterparts, the combined cadmium in QD Vision TVs and the power plant emissions associated with their use is actally lower than that associated with conventional flat screen TVs. In other words, using cadmium in quantum dots for production of more energy-efficient displays can actually results in a net reduction in cadmium emissions.
This is a neat trick, and it eloquently demonstrates the dangers of jumping to conclusions over risks without seeing the full picture. It does, however, depend on a commitment to responsible innovation and development that considers future health and environmental impacts.
This week at CES, the future of quantum dot televisions is certainly shining bright. With smart approaches to balancing risks and benefits, there’s no reason why this light shouldn’t continue to shine – as long as manufacturers and consumers keep their eye on the big picture.

How nanotech is changing your world


battery_sunx250By Andrew Wright – World Economic Forum

*** Editor’s Note: We couldn’t agree more Mr. Wright!

The American engineer Eric Drexler, who coined the term nanotechnology in the 1980s, is not afraid of ambitious thinking. In his 2013 book Radical Abundance: How a Revolution in Nanotechnology Will Change Civilization, Drexler imagines a 3D printer-like “factory in a box”, which could manipulate atoms precisely enough to manufacture almost anything.

We may still be far from realizing Drexler’s vision, but the field which he named is maturing quickly. Only a few years ago, nanotech was still caricatured as the preserve of crazy scientists. According to Aymeric Sallin, chief executive officer of venture capital firm NanoDimension, that has all changed and “it is now getting traction from large corporates and institutional investors. CEOs are moving from big, established companies to nanotech enterprises”.

No-needle vaccines


Nanotech is everywhere – from the needle-less Nanopatch vaccine delivery system of Vaxxas, one of the World Economic Forum’s new crop of Technology Pioneers, to the work of the Forum’s Young Scientist community member Hele Savin on making solar panels more efficient by removing impurities in silicon. So how big is the nanotech industry?

The question makes no sense, says Sallin. “Nanotech is not an industry in itself, but an enabler across all industries. By manipulating individual atoms and molecules, you can access intermediary states of matter where nature’s physical properties have changed; this is unlocking commercial opportunities from health to manufacturing, energy to farming.”Renewable Energy Pix

In medicine, especially, the promise of nanotechnology has been apparent for years but is only now coming to fruition. CEO of venture capital firm Flagship Ventures, Noubar Afeyan, explains: “If we could cure diseases with human imagination alone, we’d be done by now. You can write things down, and design them, and they should work – but reality is always more complex. For example, original approaches to creating nanomedicine often underestimated the need for targeting, so they were interacting with all kinds of things in the body.”

Targeted cancer treatment


Rice Cancer 50167An example of targeting is the nanoparticles called Accurins, developed by BIND Therapeutics, which bind only to certain types of cells. They promise to revolutionise cancer treatment, in particular. At present, the only way to get tumour-killing drugs into cancer cells is to treat the patient’s whole body, which causes side effects as the drugs interact also with healthy cells. Packaging the drugs in Accurins means they bypass healthy cells and are delivered directly to the diseased cells, where the drugs are released at a pre-programmed rate.

As Afeyan, among the company’s backers, says: “This sounded like science fiction when it was developed at MIT seven or eight years ago. Now the technology is mature, and we are limited only by the time it takes to complete clinical trials. We are in phase II, and if all goes well, in about two or three years we could start to see these treatments becoming available.”

Selecta Biosciences – like BIND, one of last year’s crop of Technology Pioneers – uses nanotech to target immune cells rather than diseased cells. Selecta has designed nanoparticles which dampen the response of the immune system to specified triggers, inducing tolerance – an approach that could help treat allergies and autoimmune diseases. While these treatments are still in the preclinical phase, results from animal tests are promising.

Ending animal tests
Sallin, meanwhile, hopes that a newly launched start-up could make animal tests a thing of the past. Emulate was set up to commercialize research by Harvard’s Wyss Institute on creating “organs-on-chips” – translucent flexible polymers, about the size of a computer memory stick, which mimic the workings of human organs such as the lung, heart and intestine.

As Sallin explains, testing a new drug on human cells in a lab doesn’t replicate the stresses the molecule will be exposed to in a real body – from the blood flow, the immune system and so on. And even if a molecule copes with those stresses in the body of a mouse or a rat, it often fails to do so when eventually tested on people. Replicating a human body, by linking various organs on chips together, could make the process of testing new treatments – which currently takes years and costs millions of dollars – much quicker, cheaper and more reliable.

Sallin adds: “Further down the line, one could even imagine personalized chips made from patients’ own cell samples. You could test whether a particular drug will work on a particular individual before administering it to them, opening the door to highly customized treatments.”

The difficulties of making the leap from theory to the complexities of the real world are not limited to medicine. With nanotech applications in industry, the challenge is how to take what works in the lab and scale it up to be commercially viable.

Like a cake for 8,000 people


Nicole Grobert, Professor of Nanomaterials at the University of Oxford
, likens laboratory work to baking a cake for eight people and commercial production to baking the same cake for 8,000: “It’s not as simple as buying a thousand times as many eggs and bags of flour and sugar. For a start, you’d need a vastly bigger cake tin, one that wouldn’t fit in your oven – so you’d need to build a much bigger oven. And you might find that the temperature in a bigger oven would be less uniform. It could be a lot harder to fine-tune the cooking process so your cake isn’t burnt on the outside and raw in the middle.”

An example: Joule Unlimited is working to produce biofuel from industry’s waste carbon dioxide, using solar power and genetically-modified photosynthetic bacteria as a catalyst. Its 1,200-acre demonstration plant in the New Mexico desert is already producing ethanol at about three-quarters of the theoretical maximum in the lab – around 25,000 tonnes per acre per year, which would make it cheaper than ethanol produced traditionally from sugarcane, biomass or corn. The same technique is also producing diesel in the lab, but there is further to go before this becomes viable at large scale.

As Afeyan, the company’s co-founder, says: “It’s a question of going through optimization and better process engineering steps, to try to scale up from the lab to commercial production.”

Smarter solar


Sallin’s portfolio includes View Glass, which employs over 300 people in rural Mississippi making electrochromic glass. The glazing tints itself either automatically, following the position of the sun, or on demand using a smartphone app, making the building more comfortable in direct sunlight while saving money on air conditioning and blinds. As he says: “This is one example of how nanotech is disrupting entire market places and creating value in industries which have not seen any big new ideas for the last two or three decades.”SA Solar 5 191b940e-6e05-402a-bfbb-3e7be5f8a46f_16x9_600x338

Often, fundamental breakthroughs can have applications in multiple, very different areas. Returning to BIND Therapeutics, Sallin – another of the company’s backers – points out that the nanoparticles which target diseased cells can be pre-programmed to release their disease-treating drugs at an optimal rate. What other uses might there be for a polymer with these properties? Sallin mentions irrigation: “There are lots of places in the world – such as North Africa – where there are fertile soils and theoretically enough water throughout the year to grow food, but not spread over the right timespan. When you have prolonged periods without rainfall, you need irrigation. The problem with irrigation, however, is that much of the water either evaporates or gravitates through the dirt and doesn’t benefit the crop.

“So suppose you can take this polymer which controls the release of a drug on a cancer cell, and use it to capture water, turn it into a gel and release it in a controlled way over extended periods. More and more land would become available for agriculture.”

The idea illustrates how nanotechnology seems to lend itself to conceiving of ambitious goals. But it also shows, in Afeyan’s words, how “nanotech has moved from being a curiosity to a capability, part of our arsenal of tools. And that’s a good thing”.

Nanotechnology: From Fuel Cells and ‘Artificial Synthesis’ to Carbon Capture and Graphene Hybrid Flexible Solar Cells


seo-speed-of-lightMuch like the changes plastics and polymers brought to our world, (making things easier to make, stronger, cheaper, etc.) applied nanomaterials are being fabricated and integrated into large, mature existing markets, while also facilitating emerging products and technologies that are being developed by a very deep field of mature and financially capable companies.

Where is Nanotechnology Used Today?

Nanotechnology, Nanomaterials will touch almost every aspect in our everyday lives from Nano-Medicine and Consumer Electronics to Energy Solutions and Advanced Fabrics. Nanotechnology is currently being used in many commercial products and processes. For example, nanomaterials are used to manufacture lightweight, strong materials for applications such as boat hulls, sporting equipment, and automotive parts. Nanomaterials are also used in sunscreens and cosmetics. Nanostructured products are used to produce space-saving insulators which are useful when size and weight is at a premium—for example, when insulating long pipelines in remote places, or trying to reduce heat loss from an old house.

Nanostructured catalysts make chemical manufacturing processes more efficient, by saving energy and reducing waste. In healthcare, nanoceramics are used in some dental implants or to fill holes in diseased bones, because their mechanical and chemical properties can be “tuned” to attract bone cells from the surrounding tissue to make new bone. Some pharmaceutical products have been reformulated with nanosized particles to improve their absorption and make them easier to administer.

Opticians apply nanocoatings to eyeglasses to make them easier to keep clean and harder to scratch and nanoenabled coatings are used on fabrics to make clothing stain-resistant and easy to care for. Almost all high-performance electronic devices manufactured in the past decade use some nanomaterials. Nanotechnology helps build new transistor structures and interconnects for the fastest, most advanced computing chips. All told, nanotechnologies impacted the global economy by $251 billion in 2009. This figure is estimated to grow to $3.4 trillion by 2015 (Lux Research, 2014).

It is our opinion at Genesis Nanotechnology, Inc. that Nanotechnology has not only “come of age” but will be the driving force behind the next Industrial Revolution, from Energy to Water, Electronics to Health … Nanotechnology will lead the way and solve many of the daunting challenges we face, creating vast new commercial opportunities.

Nanotechnology Makes LED Displays Brighter, Clearer & Cheaper to Make


1-LED's shutterstock_146111753Nanotechnology attempts to control atoms and molecules on the scale of less than 100 nanometers. A nanometer is one-billionth of a meter. So, imagine trying to build a computer chip or microscopic device in this small space!

Stephen Chou has dominated the field of nanotechnology in recent years. He is a Packard Fellow, an inductee of the New Jersey Technology Hall of Fame and has published almost 300 scientific papers. He currently holds 15 patents and has applied for over 40 more. Furthermore, Chou is the founder of Nanonex Corporation and NanoOpto Corporation.

1-LED's shutterstock_146111753

In 2012, Stephen Chou used nanotechnology to show researchers and manufacturers how to almost double the efficiency of solar cells. Now, he has turned his attention to the construction of LEDs (light-emitting diodes). Consequently, consumer products may soon boast that their LED displays are 57 percent more energy efficient, 57 percent brighter and deliver 400 percent more clarity. This technology will be especially important for future smartphones. And while Apple fans are (rightfully so) raving over the new iPhone 6, Chou says the new technology will produce screens that are easier to see, much more defined and will last up to 10 times longer.

Nanotechnology for LEDs

Current nanotechnology allows for working at the level of about 90 nanometers; however, Chou’s technique will reduce that playing field down to 10 nanometers. Chou’s team can actually bend light at a sub-wavelength dimension, which enables them to ensure that more of the light emitted reaches the surface.

The physical structure incorporated is known as PlaCSH (plasmonic cavity with subwavelength hole array). With PlaCSH, Chou’s team achieved a light extraction level of 60 percent, reports ScienceDaily, which is an incredible leap for the 3 percent that we see in cell phones currently. Chou states, “New nanotechnology can change the rules of the ways we manipulate light. We can use this to make devices with unprecedented performance.” That means you will see more clearly, not just on your smartphone screen, but with any device—whether automotive, instrument-fixed or appliance-based that incorporates LED lighting.

Other Uses of Nanotechnology

Chou’s work also has been applied to the world of medicine. One of the areas where nanotechnology may apply is immunoassay, which is a standard test used in the early detection of medical conditions like Alzheimer’s disease and cancer. Thanks to nanotechnology, immunoassay could become 3 million times more sensitive.

Immunoassay uses biomarkers, or the chemicals linked with diseases, and when those markers are present, then the test produces a fluorescent glow, explains Princeton’s School of Engineering and Applied Science. The brighter the light, the more biomarkers that are present. Nanotechnology will help make this process even more sensitive because it can detect fainter traces of light. Chou and other researchers at Princeton created gold and glass structures that were small enough to be seen with an electron microscope and increased the flueorescence signal of the immunoassays. Overall, this means your chances of early detection of a serious disease would increase exponentially.
