Definition of nanoscience and nanotechnology
It was felt that nanoscience could be defined as over 200 years old, and that
nanotechnology was merely an enabling technology. As such, the exact definition
of nanotechnology was felt to be unimportant. The point was made that in the
search for improving the properties of materials, size was not necessarily the
over-riding factor. A solution to a problem is what is sought, rather than a
reduction in size scale, although this can in some situations lead to an answer.
Is there a nanotechnology industry?
It was thought that the only pure nanotechnology industry today was probably
in analytical tools for the measurement of nanoparticles, film thickness, DNA,
and screening drugs and chemicals for pharmaceutical purposes. Industries that
merely utilise nanotechnology in complex applications such as mobile phones
or computers should not be classified as nanotechnology industries. It was also
felt that manufacturers of nanoparticles should not be categorised as belonging
to a nanotechnology industry as a nanoparticle is not an application.
Evolution or revolution
There was a feeling that nanotechnology will not change the nature of industry.
Technological progress would proceed in an evolutionary manner, with a gradual
substitution of products over time. This would result in small changes to the
structure of industries, and not the radical shake-up predicted by some. The
point was made that just because nanoparticles may be new, this did not mean
they would automatically be used. Like any other new technology, nanotechnology
has to provide a better and cheaper product alternative to that already in use
before substitution will take place.
