Enhanced antibacterial activity of TiO(2) nanoparticle surface modified with Garcinia zeylanica extract

BACKGROUND: The antibacterial activity of 21 nm TiO(2) nanoparticles (NPs) and particles modified with Garcinia zeylanica (G. zeylanica) against Methicillin resistant Staphylococcus aureus was investigated in the presence and absence of light. RESULTS: Surface modification of TiO(2) NPs with the ads...

description BACKGROUND: The antibacterial activity of 21 nm TiO(2) nanoparticles (NPs) and particles modified with Garcinia zeylanica (G. zeylanica) against Methicillin resistant Staphylococcus aureus was investigated in the presence and absence of light. RESULTS: Surface modification of TiO(2) NPs with the adsorption of G. zeylanica extract, causes to shift the absorption edge of TiO(2) NPs to higher wavelength. TiO(2) NPs, G. zeylanica pericarp extract showed significant bactericidal activity which was further enhanced in contact with the TiO(2) modified G. zeylanica extract. CONCLUSIONS: The antimicrobial activity was enhanced in the presence of TiO(2) NPs modified with G. zeylanica and with longer contact time.
