Book Report: something on Nanotech

This is going to be a rather lack luster book report, but I felt I should write it anyhow. I read a book recently on the ethics and pitfalls of Nanotechnology - I think it was an Earthscan book if that helps at all. It was a great series of chapters from many different sources all about the future developments of nanotechnology looking at the ethical development of the industry, and many of the up and coming developments - soooo exciting (I love science) . I found the book - its called Nanotechnology: Risk, Ethics and Law, and overall it was great for an overview of the future of this field.
.

Anyhow, the only thing that I can actually remember from the book - is that we should approach the developments in nanotechnology with caution, as the full ramifications of each of the new technologies are unknown, and when we are looking at particles at that scale, it could have dramatic effects on life from the cellular level. That, and that the name for the thing we should be concerned about is AWESOME - 'Free Radicals', I want to be a 'Free Radical' - if I was cool/geeky enough to have a band I would name it 'Free Radicals', I can picture the punk inspired font right now...
