NANO: WHERE ART MEETS SCIENCE

August 18, 2004
		Through an interactive exhibit, professors James Gimzewski and Victoria Vesna from the University of California at Los Angeles hope to inform visitors about the basics and uses of nanotechnology. The two answer your questions on nanotechnology, and how art can help us better understand the complex field.

Online NewsHour Special Report: Nanotechnology: Where Art and Science Meet Forum Introduction What are the potential applications for nanotechnology in medical science? What are some examples of the use of nanotechnology in practical applications today? What about the dangers of novel, tiny molecular assemblages interacting in unforeseen ways with the biota? What are the theological implications of nanotechnology? Is this exhibit going to be traveling to other art museums or "nano" conferences around the country?	Joseph C. Poore of Bristol, Tenn., asks: What about the dangers of novel, tiny molecular assemblages interacting in unforeseen ways with the biota? Professors James Gimzewski and Victoria Vesna respond: Science fiction novels such as Michael Chriton's best selling novel Prey have contributed to a vision of nanobots getting out of control. We are far from such a scenario that is in fact highly unlikely, but this should not mean that there are not potential dangers that are not even considered at this point. It is important for the public to remain informed of the developments in nanotechnology and participate in the debate about its' uses and potential misuses. For instance, right now we know that materials and chemical that are normally non-toxic can be radically shifted in their color, electronic and chemical properties by their size and shape on the nanoscale. This ability means that the traditional classification of toxilogical properties needs to include test and trials on new materials. Quantum dots and nano-tubes are cases in point. These issues also relate to the biota. A powerful example from our daily life are the ecological issues around freon in refridgerators. Nanotechology has an enormous potential in reducing greengas emissions and increasing energy efficiency. The long-term effects of fossil fuels pose much greater risks and more certain damage to the planet at this moment.
