Cytotoxicity assessments of the TAFP with or without NIR irradiation and detection of ROS generation. a Cell viabilities of SKOV3 cells after 24 h co-incubation with TAFP composites at different concentrations. b Cell viabilities of SKOV3 cells co-incubated with TAFP composites at different concentrations for 6 h with or without irradiation by 1 W/cm2 NIR laser irradiation for 10 min. c Digital images of live/dead staining for SKOV3 cells treated with PBS, TAFe and TAFP composites with or without NIR laser irradiation. d ROS detection of SKOV3 cells co-incubation with PBS or TAFP with or without NIR laser irradiation. e Quantification of fluorescence intensity for SKOV3 cells at 10 min after treated with PBS or TAFP with or without NIR laser irradiation. Scale bar = 100 μm and 200 μm
