Nanodermatology: a bright glimpse just beyond the horizon - part I.

Nanotechnology is a relatively new branch of engineering that is making rapid inroads in medicine and 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. Among US patent holders in nanotechnology, the sixth largest is a cosmetics company. Nanotechnology applications have been realized in sunscreens and are being developed for the maintenance of skin health, as well as for the diagnosis and management of skin disease. This article summarizes some of the recent and anticipated advances in nanotechnology for dermatology. In part II, the author addresses the chief concerns of nanotechnology.
