    Abstract: A method for forming a metallic nanoparticle and semiconductor coated surface, such as the surface of a fiber or other material is provided. The method can include the steps of coating at least one surface of a material, for example a textile material, with a semiconducting layer, and providing metallic nanoparticles on the semiconducting layer. The steps for coating a surface of a material with a semiconducting layer can include forming a titanium dioxide film on the surface of the textile or other material. The steps for depositing and/or providing metallic nanoparticles on the semiconducting layer can include immersing a surface having a semiconductor layer into a metallic nanoparticle precursor solution, drying the semiconductor layer, and exposing the semiconductor layer on the surface to UV radiation. The metallic nanoparticles can include gold and/or silver nanoparticles. Also disclosed are surface treated materials having a semiconductor layer thereon, wherein the semiconductor layer is treated to include metallic nanoparticles. The surface treated materials may comprise surfaces of a textile material, such as fibers. The surface treated materials are anti-microbial and resistant to peeling, as well as non-toxic to biological surfaces, such as skin. Treated fiber materials may be used in garments, masks, and other products that contact the skin, that are free of toxic/rash side effects.
