In this study, the authors investigated antimicrobial activity of TiO 2 nanoparticles (NPs) synthesised by sol–gel method. As synthesised TiO 2 NPs were characterised by X‐ray diffraction, scanning electron microscopy and ultraviolet‐visible absorption spectroscopy. The antimicrobial activity of calcined TiO 2 nanoparticle samples was examined in day light on Gram positive bacteria ( Staphylococcus aureus, Streptococcus pneumonia and Bacillus subtilis ), Gram negative bacteria ( Proteus vulgaris, Pseudomonas aeruginosa and Escherichia coli ) and fungal test pathogen Candida albicans . The synthesised TiO 2 NPs were found to be effective in visible light against Streptococcus pneumonia, Staphylococcus aureus , Proteus vulgaris, Pseudomonas aeruginosa and Candida albicans .
