Nanodermatology: a glimpse of caution just beyond the horizon - part II

Nanotechnology is a relatively new branch of engineering and medicine that is making rapid inroads in dermatology. Nanotechnology applies the unique properties of matter on the nanoscale (1000 nm and smaller) for the purposeful design of new materials. Dermatology is already one of the leading beneficiaries of nanotechnology. In Part I of this series, we discussed the benefits of nanotechnology in dermatology. In Part II, we discuss some of the risks. Matter on the nanoscale has the potential for significant chemical volatility, which carries with it an increased risk of cellular and tissue damage. This article summarizes some of the theoretical safety concerns regarding nanotechnology and offers suggestions for addressing them.
