Enhanced antibacterial activity of TiO nanoparticle surface modified with extract.

Background: The antibacterial activity of 21 nm TiO nanoparticles (NPs) and particles modified with () against Methicillin resistant was investigated in the presence and absence of light.

Results: Surface modification of TiO NPs with the adsorption of extract, causes to shift the absorption edge of TiO NPs to higher wavelength. TiO NPs, pericarp extract showed significant bactericidal activity which was further enhanced in contact with the TiO modified extract.
