Nanotechnology: Environmental Boon or Boogyman?

The Fullerene "buckyballs" nineteen-ninety nano-product, proved to be both a fantastic form of graphite-like lubricant, and a highly toxic substance, because of it's versatile atomic-linking properties, usually high with carbon in the first place.

This was both a notable milestone, and a typical sampler of the question.

On one hand, nano-scale molecular manipulation, is a milestone setter for electronics and data storage, but chemically, it represents the abundance of structures, in a scale which is hard to "tame" for human consumption - such as the suggested venues of drug-delivery and medical use in general.

I didn't get to the linked article until it had been removed.

If nanotech is to become a tool for remediation it has to be a technology that is both suitable and cost competitive with other remediation techniques. One might find that nano solutions are more viable than, say biotech, in some environments, but not in others.
