This question is a tricky one because “Nanotechnology” is such a broad and vague term. Four researchers wrote in to give their views regarding the meaning of Nanotechnology and when we will begin to benefit from it.

“It is difficult to give a precise answer to this question because the term ‘nanotechnology’ is not well defined.

It means different things to different people. Perhaps the broadest definition of a ‘nanostructure’ is something which has a physical dimension smaller than 0.1 micron, or 100 nanometers (billionths of a meter).

Using this definition, integrated circuits will qualify as nanostructures shortly after the turn of the century. Current integrated circuits have minimum dimensions on the order of 0.35 microns.

Based on current rates of development, people have projected that around the year 2005 companies will be manufacturing in high volume integrated circuits that have dimensions around 0.1 micron. These numbers refer to…
