Abstract

Highly effective antimicrobial agents are critical to human health. In this study, we treated nano titanium sensitized with different dose of Fuchsin Acid, Alizarin red and Tartrazine. We investigated the antimicrobial activity of Anatase-sensitized with different organic dyes from same ratio as 0.2, 1, 2 Wt. %. Different dyes sensitizing nano titanium dioxide all exhibited different strong antimicrobial capacity than pure-titanium dioxide. Modification methods of Titanate were adopted to broaden the photo absorption region and improve photo-quantum efficiency, which is a useful way to enhance the antimicrobial capacity.
