Applications of Nanometals in Cutaneous Infections

Nanoparticles have been largely applied in industrial fields, engineering, and medicine, and are considered as efficient biotechnology tool. Metallic nanoparticles are incorporated into different material with biological properties mainly as antimicrobial. Nanoparticles are the particles with size between 1 and 100 nm being used to different goals due to the beneficial properties. According to the size, NPs can be selected for each function. NPs smaller than 4 nm can usually penetrate and permeate intact skin and reach deeper organs; however, NPs greater than 45 nm cannot penetrate or permeate into the skin. Nanometals have a great potential to different applications in medicine, due to their properties and features. One of these applications is on cutaneous infections, such as acne vulgaris, mycoses, cutaneous leishmaniasis, and wound, which will be discussed here in detail.
