How can ab initio simulations address risks in nanotech?

Amanda S. Barnard

Significant numbers of consumer products based on nanotechnology are entering the market, and large quantities of nanoparticles are now being produced annually. In producing these products, we are confronted with the vexatious reality that the very same physical features that provide the sensitivity and reactivity that are essential for many of these applications may also be a disadvantage when we consider the possible risks and hazards associated with these products.
