Nanotechnology is a new branch of engineeringconsisting of the usage of nanoscale particles (100 nm andsmaller). Nanomedicine is the application of nanoscale technologiesfor diagnostic and therapeutic purposes in medicine.Nanodermatology, nanotechnology applied to dermatology,represents one of the most advanced field for which anincreasing interest, both economic and scientific, is rising. Theskin is the first point of contact for a whole host of nanomaterials,ranging from topical preparations, articles of clothing andhousehold products, to sporting goods and industrial manufacturedgoods. Applications of nanomedicine in dermatology
include new direction in medical diagnosis, monitoring andtreatment. Gold nanoparticle, quantum dots and magneticnanoparticles are used in non-invasive nanoimaging of highresolution
dermoscopy, microscopy, nanopunch, and spectroscopy,offering advanced diagnostic and therapeutic modalities.Nanotherapeutics has been considered in immunotherapy,
genetherapy, and drug therapy. In drug therapy, because ofsize reduction or encapsulation of drug particles, the therapeuticpotential of water insoluble and unstable drugs improve,and also facilitate the delivery of small molecules across blood,skin, nails, and pilosebaceous unit.
