a Schematic illustration on the preparation of thermally reduced TiO2 nanoparticle (i.e., R-TiO2) from TiO2 nanoparticle (i.e., TiO2) and its generation of surface-bound superoxide radical in the dark. b, c Survival ratios of b B. subtilis and c E. coli cells after treatment with R-TiO2 and TiO2. d Viability ratios of NIH-3T3, Raw 264.7, and Ana-1 cells after R-TiO2 treatment. Each in vitro antibacterial and cell viability assay was carried out in triplicate and the reported results are averages of two independent trials. Plots on source data are provided as Supplementary Figures. Source data are provided in the Source Data file.
