The sol-gel method is a powerful tool to functionalize are broad range of different materials by application of inorganic coatings. One important functionalization is the antimicrobial activity. By application of an antimicrobial sol-gel coating, the coated material is able to decrease the growth of bacterial, fungi or other microorganisms. Also the complete elimination of microorganism is possible. The sol-gel approach can realize the antimicrobial properties using different concepts as – contact action, controlled release or photoactivity. In following chapter, these concepts are explained in detail and a broad overview on different useful sol-gel materials is given.
