Antibacterial Properties of Sol-Gel Derived TiO2 Nanoparticles

Abstract

Efficient synthesis of antibacterial and antifungal titanium dioxide nano powders offers new advanced properties and opportunities for industrial applications. In the present study, TiO2 nano particles were synthesized by sol-gel method using aqueous and alcoholic solutions of titanium tetraisopropoxide (TTIP). The effects of solvent type, support material (calcite, talk, zinc borate, silica) and drying temperature on antibacterial/antifungal and structural properties namely the average particle size and surface area of titania particles were investigated.
