Florida Governor Jeb Bush has proposed spending $100 million in 2002 on a technology initiative to create Centers of Excellence at Florida universities, according to a number of recent press reports. The program would include nanoscale science and technology as a major component.

If passed, the Florida program, which resembles programs already in place in California, New York, and Texas, would be one of the largest government-funded nanotechnology programs in the United States, trailing only Californiaís program.

An article in The Scientist ("Nanotech Dreams", by Senior Science Editor Jeffrey M. Perkel; 4 March 2002) offers a general overview of nanotechnology from a life science perspective. The article presents some background on the ideas of Richard Feynman and Eric Drexler (mixed with a few hoary science fiction clichés and comments from nay-sayers to the idea of advanced molecular nanotechnology, such as Richard Smalley) before focusing on current research in several areas. "It's an unusual field," says Chad A. Mirkin, a professor of chemistry and director of the Institute for Nanotechnology at Northwestern University. "It's a field that focuses on a scale rather than on a material. So it affects everything."

The article also quotes Robert A. Freitas Jr., a research scientist at Zyvex Corp. and author of Nanomedicine, about the distance between long-term visions for nanotechnology and current capabilities: "My vision of nanomedicine ranges from the near-term to the far-term," he says. "I look at the things that can't be done for 20 years as a vision, as the ultimate goal, as a wonderful thing, way out there, that we can grasp for. And in the meantime, we have to do all the things that are necessary to get up to that point, and there's an awful lot of work to be done, and lots of work for everybody."

The bulk of the article actually focuses on various companies attempting to create biosensor systems using various micro- and nano-scale technologies, and nanostructured materials that may have therapeutic applications. The article does concludes by returning to disputes over the feasibility of nanorobotic systems, and gives greater play to the more conservative view:

Northwestern's Mirkin bluntly surmises, "I think it's baloney . . . I think a lot of people, including scientists, try to say, 'This is pie-in-the-sky. A lot of it is really far out. It's going to have a big impact, but it's not going to be realized for 25 to 50 years,'" says Mirkin. "That's wrong, and it's also wrong to say it's going to revolutionize everything in the next couple of years. Something in the middle is correct."

An article in Dallas-Ft. Worth TechBiz ("Local medical device industry could boom with right political support", by Pavan Lall, 21 January 2002) describe innovative companies in the medical device industry in Texas. The article includes a brief nod toward the potential medical applications of nanotechnology:

Nanotechnology will help shrink medical devices, said Christopher Chavez, president and chief executive at Plano-based Advanced Neuromodulation Systems Inc. ìThe technical issues of nanotech will be resolved downstream, and the improvement of devices will be based on a synthesis of different technologies,î he said. . . . In about 20 years, through a better understanding of the central nervous system, electricity will be accepted as a digital drug, Chavez said. The shrinkage of medical devices will stimulate other technologies as well as make the broad-based use of drugs and chemicals obsolete. ìMachinery and electrode miniaturization will result in very elegant solutions that will be tremendously intelligent,î he said.
Jim Von Ehr, president and chief executive of Richardson-based nanotech company Zyvex Corp., agreed. ìWe have been talking with a number of doctors about things in the medical area and have looked at micro-devices and micro-diagnostics. In the future, there could be a variety of micro-devices that will detect bacteria in a system, chop it into pieces and digest it or even carry oxygen better than a cell in a bloodstream can.î To successfully implement different aspects of medical devices in production, one must understand biological content as well as the relation to software and bioinformatics, Von Ehr said.

It is worth noting that Robert A. Freitas Jr., author or Nanomedicine, the first book-length technical discussion of the potential medical applications of molecular nanotechnology and medical nanorobotics, is a Research Scientist with Zyvex.

An extensive article in the Ontario, Canada National Post ("Small Miracles", by Margaret Munro, 21 January 2002) provides an interesting, if somewhat skeptical, look at nanotechnology in Canada and the United States. While dismissing speculations about advanced molecular nanotechnology as "the stuff of fiction", Munro writes "there is clearly a revolution afoot", but:

Scientists say the revolution will be gradual. "The hype is just that," says Robert Wolkow, a research officer at the National Research Council in Ottawa and one of the country's leading nanotechnologists. "Many really remarkable things will happen. But they're not going to happen next year or even in five years," he says. A more realistic time frame is 10 to 20 years before nanotechnology dramatically changes our lives. But when the revolution comes, says Wolkow, "it will be fantastic."

In addition to profiling a number of interesting nanotech research projects, the article briefly mentions the contention over the feasibility of molecular assemblers that resulted from the September 2001 special nanotech issue of Scientific American, and quotes skeptical Canadian researchers.

The November/December issue of Micro Magazine, a trade for the semiconductor manufacturing community, has an article on nanotechnology ("When Micro Meets Nano: Small things considered", by John Conroy). Not surprisingly, the article focuses more on short-term possibilities for molecular-scale transistors, carbon nanotubes, and atomic layer deposition of interest to the microelectronics and semiconductor industry. It also presents some mildly pessimistic comments on the possibility for more advanced nanorobotics from Susan Sinnott, a researcher in the Department of Materials Science and Engineering at the Unviersity of Florida and co-chair of the Ninth Foresight Conference on Molecular Nanotechnology in November 2001.
