<p>A dual action antimicrobial film comprises a visible transparency of greater than 75% transmission at visible light wavelengths of between 400 and 900nm, the film comprising a coating solution of soluble Ti02 and a metal species wherein the dual action antimicrobial activity comprises metal ion diffusion release and Ti02 photocatalytic activity. The dual action antimicrobial film is a smooth film displaying regulated isotropic crystal growth and comprises a roughness factor (Ra) of less than 1.5nm. The antimicrobial action of the film is active under both light and dark conditions and the dual action antimicrobial film prevents biofilm formation when the film is deposited on a substrate.</p> |
