Nanosized particulate systems for dermal and transdermal delivery.

Nanosized particles have received much attention in industry, biology, and medicine. Today nanotechnology is finding growing applications in pharmaceutical formulation for skin delivery. This review surveys some of the approaches in the field of nanosized particulate systems for both dermal and transdermal delivery, highlighting the nanosized microemulsion, vesicular systems, solid lipid nanoaprticles (SLN), nanostructured lipid carriers (NLC) and polymeric nanoparticles.
