Foresight Nanotech Institute Weekly News Digest: May 3, 2006
In this issue:
Foresight has articulated six critical challenges that humanity faces which can be addressed by nanotechnology. In the Weekly News Digest we identify news items, research breakthroughs, and events citing current research and applications providing the stepping stones to solutions to these challenges.
Foresight note: Here's news of additional funding for solar power employing nanoscale materials. Hopefully this funding activity will lead to large-scale application.
Headline: Solar cell supplier Innovalight raises $7.5 million
Innovalight Inc., a privately held firm focused on developing low-cost, nanotechnology-based printed solar cells, has raised an additional $7.5 million in private equity financing.
This Series B financing led by Harris & Harris Group, Inc., includes investment from existing investors Apax Partners, ARCH Venture Partners, Sevin Rosen Funds and Triton Ventures.
Innovalight plans to employ this additional capital to accelerate development of low cost, lightweight solar cells using a proprietary silicon ink-based technology.
Over 90 percent of solar energy modules are made from crystalline silicon wafers that are costly to produce and in critical short supply because of competing demand from the semiconductor industry.
"Today, solar energy represents a paltry two-hundredths of one percent of the total global electrical energy generated because current production methods are still too expensive," said Conrad Burke, president and chief executive. "Innovalight is developing a technology that could ultimately reduce the cost of producing solar-generated electricity tenfold."
Foresight note: This radio program discusses nanotechnology and desalination.
Headline: Can nanotechnology make saltwater drinkable?
Radio host Deborah Byrd: This is Earth & Sky. Some places are struggling to have enough freshwater to sustain a growing human population.
Radio host Joel Block: That includes some cities like Phoenix — the state of California — the Middle East — and, ironically, the coasts of many nations. Especially along the coasts, desalination can help. That's the removal of salts and other substances from saltwater to produce freshwater. Desalination is expensive. But it's already widely used in the Middle East, North Africa and the Caribbean, and California and Texas are planning desalination projects.
Radio host Deborah Byrd: We spoke with Kamalesh Sirkar at the New Jersey Institute of Technology. He's using a new technology — nanotechnology — to purify saltwater. The most commonly used desalination techniques are called "distillation" and "reverse osmosis." The nanotech technique is also expensive, Sirkar said, but it should work faster than other techniques.
Radio host Joel Block: He's now trying to make it more energy efficient, and he's trying to solve the problem of scaling — a process in which salts and minerals clog up the system.
Foresight note: This research details how quantum dots can locate the blood source of cancer tumors, making it easier to surgically remove them.
Headline: Targeted quantum dots image tumor blood supply
Using polymer-coated cadmium telluride/zinc sulfide (CdTe/ZnS) quantum dots targeted to a molecule found on newly growing blood vessels, a team at the Stanford University Center of Cancer Nanotechnology Excellence (CCNE) has shown for the first time that quantum dots can image a tumor's blood supply. This development holds promise for the development of new ways of detecting cancer as well as identifying the edges of a tumor during surgery.
Reporting its work in the journal Nano Letters, a group of investigators led by Xiaoyuan Chen, Ph.D., Sam Gambhir, M.D., Ph.D., and Shan Wang, Ph.D., all project leaders in the Stanford CCNE, described its construction of a CdTe/ZnS quantum dot decorated with 30 to 50 copies of a small protein, or peptide, known as RGD. This peptide binds specifically to a much larger protein, called αvβ3, found on the surfaces of new blood vessels growing in response to tumor cell signals, as well as on some tumor cells. Tests with cultured human tumor cells confirmed that these quantum dots bound tightly only to those cells that have αvβ3 on their surfaces.
Based on these promising results with isolated cells, the investigators explored whether these targeted quantum dots would bind to human tumors growing in mice. In fact, tests with tumor-bearing animals showed that the quantum dots were visible in tumors within 20 minutes after injection. The fluorescent signal from the tumor-bound quantum dots peaked at six hours after injection, and optical images clearly outlined the tumors against a very low fluorescent background. Subsequent microscopic examination of the tumors showed that the quantum dots were congregated on the blood vessels growing in and around the tumors.
Foresight note: This conference features several speakers on food and nanotechnology. Here we highlight one of the presentations at this event.

Christine Peterson, Vice President of Public Policy, will also speak at this meeting.
Foresight note: Physicists observe "contrary conductivity" at the nanoscale.
Headline: Tiny wires trigger electric reversal
Physicists have observed an unexpected reversal of conductive behavior in ultracold, ultrathin zinc wires.
Typically, a metal wire more readily superconducts, or transports electricity without resistance, when it spans superconductive electrodes. However, that wire loses its superconductivity if strung between electrodes of normal metals. Yet in recent experiments, ultrathin zinc wires did just the opposite: They conducted normally when between superconductive electrodes but became superconductive when between normal electrodes.
The reversal is "very stunning, very surprising," says theoretical physicist Dung-Hai Lee of the University of California, Berkeley.
Led by Moses H.W. Chan, researchers at Pennsylvania State University in State College observed the contrary conductivity. They created nanoscale-diameter wires within pores in thin membranes of polycarbonate or aluminum oxide and then placed the membranes between pairs of metal electrodes. The electrodes' shapes made it possible to measure the electrical properties of nanowires one at a time.
Foresight note: The ISDC meeting was one of the first to cover nanotech for Space. This year they are including a space elevator panel.
Headline: Engineering Alternatives for Design and Deployment of the First Space Elevator
A space elevator panel presentation at the Space Development Conference that will be held in Los Angeles on May 4-6, 2006 will feature leaders in space elevator development.

Nanotech Events & News
Headline: Scientist warns of nanotechnology dangers
A British scientist is warning that hundreds of nanotechnology products are about to go on sale despite a lack of biological safety testing.
Nanotechnology products — containing materials that are 10,000 times smaller than the width of a hair — are already being used in numerous products, from medical bandages to golf clubs and paints.
Edinburgh University Professor Anthony Seaton, one of Britain's leading environmental health experts, says concerns that tiny particles from the products might cause respiratory, cardiac and immune problems had not been properly assessed, The Scotsman reported Wednesday.
Speaking with the newspaper ahead of a presentation he gave Tuesday at the Nanoparticles for European Industry conference in London, Seaton said that recommended nano testing "simply hasn't happened."
A recent report from a U.S. science watchdog suggested there are already 200 products containing nanoparticles on the marketplace, with hundreds more to be introduced during the coming year.
Headline: A Humboldt Award for Lehigh University's Martin Harmer:
Martin Harmer, director of the Center for Advanced Materials and Nanotechnology (CAMN) at Lehigh University, has been awarded a Humboldt Research Award for senior scientists by Germany's Alexander von Humboldt Foundation. The international honor, one of the most prestigious given by Germany, recognizes Harmer's lifetime research achievements in materials science and engineering.
Harmer, a professor of materials science and engineering at Lehigh, is world- renowned for his studies of the properties of structural and electronic ceramic materials and their control at the micro- and nanoscale. He is particularly interested in developing novel transparent materials and nanomaterials with multi-functional properties. Currently, he is studying the sintering behavior of nanoparticles of gold and iron oxide, and the mechanism of the conversion of polycrystalline alumina into single crystal sapphire for lighting applications.
As director of Lehigh's CAMN, Harmer leads a variety of projects. In one, a multi-disciplinary team of Lehigh researchers is working with peers from Harvard, Rice, Georgia Tech, UCLA and the Illinois Institute of Technology to study the economic and environmental impact of nanotechnology. The project is supported by a five-year, $1.7-million grant from the Nanoscale Science and Engineering Center of the National Science Foundation.
"The real power of nano is evident when it supports discovery and innovation in other areas — areas such as medicine, computing, materials, and environmental engineering," says Harmer.
