Discussion Overview

The discussion revolves around the definition and framework of nanotechnology, exploring its scope, applications, and the criteria that qualify something as nanotechnology. Participants consider various interpretations, including dimensional thresholds and the implications of using the term in research contexts.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether nanotechnology should be strictly defined as atom manipulation using techniques like Scanning Tunneling Microscopy, or if it should include any technology involving components with nanometer dimensions.
  • Another participant references a government definition that considers any technology involving a device or component that is 100 mm or less in any dimension as nanotechnology.
  • A different viewpoint suggests that the term 'nano' is often applied to sub-micron technologies, like silica spheres, which may not strictly fit the nanometer scale but are labeled as such for marketing or funding purposes.
  • One participant emphasizes the unique behaviors and properties that emerge at the nanometer scale, particularly in the context of nano-optics and photonic devices.
  • Another participant proposes that the term 'nanotechnology' might be better replaced with 'nanoscience' in contemporary discussions.

Areas of Agreement / Disagreement

Participants express differing views on the definition and scope of nanotechnology, indicating that there is no consensus on a singular framework or understanding of the term.

Contextual Notes

Some definitions rely on specific dimensional criteria, while others focus on the functional characteristics of materials at the nanoscale. The discussion highlights the ambiguity and evolving nature of the term 'nanotechnology' in both scientific and funding contexts.

What do you consider to be the framework for what is called nanotechnology? At first, I thought it was only atom manipulation with Scanning Tunneling Microscopy systems (the IBM atom-man), but some use the word for work where something has nanometer dimensions, such as thin films, molecules, and of course, there's laser-sculpting. What do you think?

I tend to adhere to the government definition, which says (roughly), "any technology involving a device or component that is 100 mm or less in any dimension".
 
These days, anything sub-micron tends to be labelled 'nano', for example silica spheres (such as those found in opal) 800 nm in diameter are usually referred to as nanospheres, even though their dimensions are much more comparable to a micrometer than a nanometer. I suspect the use of the word 'nano' creates more of a buzz, and thus more of a chance of obtaining a research grant.

There is a definite transition in behaviour as one scales thing down to nanometer scales (e.g waveguides in optics for example), Nanotechnology, as I think of it are devices that work within these nano-regimes of operation.

One of the largest areas of research in nanotechnology is in nano-optics, particularly photonic crystals and other minaturised optical devices.

i think it is better nowdays to call nanotechnology nanoscience
