Nanotechnology Allied to Nitric Oxide Release Materials for Dermatological Applications

It is known that nitric oxide (NO) exerts numerous physiological activities in mammals and it is considered a key mediator in many skin disorders. NO is synthesized in human skin cells where it regulates diverse physiological mechanisms such as dermal blood flow, wound healing, skin pigmentation, and aging. The great challenge of NO-based therapies is to preserve the biological activity of this ephemeral free radical. To this end, new biomaterials have been emerging as platforms for NO release for diverse biomedical applications. This review will discuss the new strategies for releasing/generating controlled amounts of NO for several dermatological applications through the use of nanotechnology.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Univ Fed Sao Paulo, Exact & Earth Sci Dept, BR-09972270 Diadema, SP, BrazilUniv Estadual Campinas, Biol Chem Lab, Inst Chem, BR-13083970 Campinas, SP, BrazilUniv Fed Sao Paulo, Exact & Earth Sci Dept, BR-09972270 Diadema, SP, BrazilWeb of Scienc
