Foresight Nanotechnology Challenges
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.
1. Meeting global energy needs with clean solutions
Foresight note:Popular Mechanics awarded Konarka for their innovative thin photovoltaic technology. There were several non-nano innovations honored as well, so most techies will enjoy this website.
Headline: Solar Energy On a Roll
Affordable, film-thin photovoltaic plastic promises to make solar energy mainstream
News source: Popular Mechanics.com by Logan Ward
Konarka Technologies, Inc., was awarded a Popular Mechanics Breakthrough Award 2005. According to Popular Mechanics, this award "salutes the innovators who are shaping the world's future through science and technology — and new products that represent benchmarks of engineering."
Konarka chief scientist and cofounder, Alan J. Heeger and his colleagues were honored for their work in semiconducting polymers that are suspended in solution that can be treated as inks.
Konarka can "print" strips of photovoltaic (PV) plastic as thin as photographic film. As with traditional PV panels, sunlight is converted into electrical energy. The advantage over traditional crystalline silicon on a glass substrate: Konarka's power plastic is 100 times thinner, as well as more pliable, cheaper and easier to mass-produce. Imagine electricity-generating awnings, tents, roofs and even clothing.
"Solar energy is going to happen," said Heeger. "It will happen sooner and on a larger scale if we can provide a lower-cost technology." Source Alan J. Heeger Konarka
2. Providing abundant clean water globally
Foresight note: This article discusses nano-sponges that sop up specific toxins according to what the particles are coated with.
Headline: Nano-sponges for Toxic Metals
News source: Nano World By Charles Q. Choi, – UPI Technology Correspondent
Microscopic particles honeycombed with holes only nanometers wide soon could help purify industrial runoff, coal plant smoke, crude oil and drinking water of toxic metals, experts told UPI's Nano World.
The particles, made of glass or natural diatomaceous earth, are 5 millionths to 50 millionths of a meter wide and filled with holes a thousand times smaller. The surfaces of these particles can bear a variety of flavors or coatings that soak up specific toxic metals — for instance, sulfurous organic coatings attract mercury, while coppery organic coatings bind to arsenic and radioactive metals known as actinides. The particles' spongy nature gives them an incredible 6,400 square feet to nearly 11,000 square feet of surface area per gram of material with which to draw in toxins.

3. Increasing the health and longevity of human life
Foresight note: This article discusses how the collaboration of government, industry and academia will shorten the regulatory review process for nanotech cancer treatments.
Headline: Nanomaterials Laboratory tries to Remove Obstacles
News source: Small Times Magazine by Candace Stuart
Understanding how nanomaterials interact with healthy and diseased cells is critical for getting nanotechnology-based products to patients. The nanomaterials will have to be proven safe and effective. But few industrial or academic labs are competent to tackle the diversity of nanomaterials plus the dynamics of cancer.
To do that, the NCI has brought in the Food and Drug Administration and the National Institute of Standards and Technology as partners. NIST will help characterize nanomaterials such as dendrimers and quantum dots. The FDA will help determine how and when various nanomaterials might be used for treatments and diagnostics. Working together, they hope to develop guidelines and standards for the industry and avoid regulatory barriers.
"If we standardize, we can save 10 years," said Mauro Ferrari, an architect of the alliance who envisioned the lab during the planning phase. He said the lab will help determine which nanotechnologies have the best prospects for commercialization. "Being rigorous in selecting which nanotechnologies will help get them into the service of the suffering population." Source Nanomaterials Characterization Laboratory
4. Maximizing the productivity of agriculture
Foresight note: This radio interview with a noted scientist, George Whitesides, discusses how nanotech could solve several problems presented to human kind, including agriculture.
George Whitesides, the Mallinckrodt Professor of Chemistry at Harvard University, is interviewed by Earth & Sky's Eleanor Imster about nanotechnology as a tool for the 21st century.
"For example," said Dr. Whitesides "in agriculture, a major cost in agriculture is spoilage. Coating fruits and vegetables in such a fashion that one controls the rate at which they ripen, and at which CO2 and ethylene enter and leave the fruit has a great deal to do with their shelf-life and their preservation. This is a combination of chemistry, but chemistry that makes materials that have nanometer-scale functionality pores, and things of that kind." Source George M. Whitesides
5. Making powerful information technology available everywhere
Foresight note: Once again scalability is sought in applications for the information technology area. This article discusses the large scale synthesis of nanowires.
Headline: Engineers Make Standardized Bulk Synthesis of Nanowires Possible
News source: Physorg.com
Yale scientists have demonstrated a method to understand effective synthesis of semiconductor nanowires (NWs) for both their quality and quantity, according to a report published in the journal Nanotechnology.
Graduate student Eric Stern in the department of biomedical engineering, along with his colleague Guosheng Cheng, associate research scientist in electrical engineering, systematically varied and tested parameters for producing GaN NWs using an optical lithographic method as a template for testing characteristics of the nanowires.
A nanowire is an ultra-miniaturized cylindrical semiconductor, as small as 1 to 100 nanometers in diameter, and extending as long as a millimeter — or 10,000 times its thickness. One nanometer is approximately a 25-millionth of an inch. GaN was chosen for these experiments as a material commonly employed in synthesis of semiconductors.
Development of reliable NW fabrication will allow the exploration of the next steps in semiconductor miniaturization. This reported technology produces ten-times the number of NWs as previous technology and sets parameters for standardization of NWs.
"This brings nanowires to an interface with the rest of the world of semiconductor research," said Stern. "Until this point, the greatest hurdle for the technology has been the inability to produce more than individual nanowires and to have statistically reproducible synthesis so that the properties of nanowires can be explored."

Headline: First Inventory of Nanotech Environment & Health Research
News Source: Nanotechnology Now
A new inventory of research into nanotechnology's potential environmental, human health, and safety effects (EH&S) shows the need for more resources, for a coherent risk-related research strategy, and for public-private partnerships and international EH&S research collaborations. These are the key conclusions drawn from the first single inventory of largely government- funded research projects exploring nanotechnology's possible EH&S impacts.
"Nanotechnology's future depends on the willingness of government, business and public interest groups — both at home and abroad — to work together to build consumer trust and to tackle any potential health and environmental issues early. This inventory is a tremendous tool to help achieve this important goal," said Dave Rejeski, Director of the Project on Emerging Nanotechnologies.
Dear readers — When reviewing news for this digest, I often read about something that I think is cool, but it doesn't fit within the usual editorial categories of the News Digest. This section highlights a nanotech advance or idea that I think is especially cool.
This article announces a "Radical advanced nanotechnology theory." The Princeton scientist explains his theory as if he were an architect. Very easy to understand and they also credit Eric Drexler in the press release.
"If one thinks of a nanomaterial as a house, our approach enables a scientist to act as architect, contractor and day laborer all wrapped up in one," said Salvatore Torquato. "We design the components of the house ... so that they will interact with each other in such a way that, when you throw them together randomly, they self-assemble into the desired house."
