Topic: Nanotechnology for Chemical and Biological Defense

I just read an article called "Nano Defense: New book explores potential chemical and biological threats from nanoscience and nanotechnology" by John Toon in the Spring 2010 issue of "Research Horizons" (put out by Georgia Tech). It's about a book called "Nanotechnology for Chemical and Biological Defense" by Margaret Kosal.

From the article: Ironically, the mechanisms that make nanotechnology beneficial could also be part of its dark side. For instance, the ability to target cancer cells by recognizing their specific genetic sequences could also potentially be used to deliver toxins to harm healthy cells. Carbon nanotubes, useful in electronics and other technology areas, could also be used to circumvent vaccines by delivering protein cargoes directly into cells. Magnetic nanoparticles developed to draw therapeutics to diseased areas of the body could also be bombarded with electromagnetic energy to create excessive heat in the brain or other organs."

I was just wondering if anybody on this board is familiar with this book and has any thoughts on it?

Haven't read it myself, but it's a familiar dilemma. The flip side of that is that snake venom can also be used to make medicine--so perhaps research in offensive nanotech might stumble on new cures!
