Applications of Nanotechnology in Dermatology

Abstract

Nanodermatology is an exponentially growing area and this chapter provides a general overview of the potential applications of nanotechnology in derma-tology. In order to contextualize this topic, different examples of nanosystems are presented along with a brief discussion on the anatomy and physiology of the skin. Then, the significance of nanomaterials as a diagnostic tool is highlighted with several examples while the role of nanotechnology in effective, targeted, and efficient drug delivery is presented in detail. In addition, the recent and anticipated advances in nanotechnology for cosmeceuticals are also discussed. Thus the chapter covers a vast array of applications of nanomaterials in skin care. Although nanodermatology has an inevitable future, the possible toxic effects and the related safety concerns could not be neglected. Thus special emphasis is given to discuss current controversial views on cytotoxicity and carcinogenicity associated with nanomaterials.
