New technology often creates novel situations for which no ethical policy exists or seems immediately obvious. In an area as broad as nanotechnology, there will be a range of possibilities for use and abuse. As a result, it is important to separate fact from fiction when considering how to formulate new and appropriate ethical policies. This book provides an introduction to the field; it first provides the reader a foundation in the basics of nanoscience as well as ethical principles, and then covers the most talked-about issues.
