Fig. 11From: The application of titanium dioxide, zinc oxide, fullerene, and graphene nanoparticles in photodynamic therapy[Taken from references (Zhao et al. 2015, 2016)] 1O2 quantum yield determination a at different time points and b at various concentrations for TSSP–TiO2 NPs and TSPP and TiO2 alone. The 1O2 quantum yields correspond to the 1,3-diphenylisobenzofuran (DPBF) capture rate of 1O2 Back to article page
