Titanium dioxide (TiO2) and cerium (Ce) doped TiO2 nanoparticles were prepared by the sol-gel method using titanium tetraisopropoxide and cerium (III) nitrate hexahydrate as the precursor materials of TiO2 and Ce, respectively. The bond configuration and anatase phase of the TiO2 nanoparticles were analyzed using Fourier transform infrared (FTIR) spectrum in the wavenumber range from 400 to 3800 cm-1. The antimicrobial activity and zone of inhibition of pure and Ce doped TiO2 nanoparticles on E. coli strain were investigated. Doped TiO2 nanoparticles showed elevated levels of antimicrobial activity than pure TiO2 nanoparticles. From these comparative studies, we have found that cerium doped TiO2 nanoparticles possess high bactericidal activity which was confirmed by Colony Forming Unit (CFU) with and without TiO2 nanoparticles inoculated on LB agar. This inhibition was further confirmed by Kirby-Bauer method and growth curve studies.
