A handful of decades ago everything was micro That was follows by the dot-com craze. Today it`s nano-this nano-that a nanometer is one-Billionth of a meter oand it takes about three to ten atoms to span the length of a nanometer however the prefix nano has been attached to dozens of words all of of which carry a host of different meanings Truth be told chemists have beenworking on the nanoscale from the eginning in the last decade we have heard about scaling machines down to the nanoscale an unfortunate image since thee machines while remarkably efficient on the macroscale are highly problematic on the nanoscale We hear about biochemists and protein engineers discussing nature as a superior analogy since nanoscale construction is what nature does We hear about directed assembly as electron microsopists push molecules around producing nanograffitti and small works of art. We hear about experts in biotechnology using self assembly to get pieces to build themselves into bigger things serving as the building blocks of new machines. As nano-hype shows there`s a lot of money to be made in nanotech and enthusiastic advocates as well as those who loudly oppose get the most attention Attention gets researchers their grants universities their budgets and businesses their investors Extraordinary exaggeration-"Hype` surrounds al things nano and antinano The claims and counterclaims are everywhere. The public and the private sectors need a guide to help them understand this nanotech buzz for what it is rather than what it claims to be especially when there is some evidence to suggest that environmental safety and human health may be at risk.
