Nanotechnology and dermatology: benefits and pitfalls

Nanotechnology is the study of purposeful design in the size range of 100 nm and smaller. Discoveries stemming from nanotechnology have led to improvements in materials and devices for industrial and consumer use. The unique properties of nanoscale matter, and the ability to engineer precisely targeted function have led to a great deal of interest in medical research in nanotechnology. Recently, the skin care industry has emerged as the leader in patents issued for nanotechnology. A range of products have been developed or are being developed for the maintenance of skin health, and the diagnosis and management of skin disease. Matter also acquires a greater potential for volatility and unfavorable reactivity on the nanoscale. The skin is the first point of contact for most nanotechnologies and thus may be an early and prime target for nanotoxicity. This review discusses some of the important benefits and risks of nanotechnology within a dermatologic context.
