PDT performance with the assistance of homologous targeting. A Relative cell viability (%) of HOS by various treatments. B Aggravated mitochondrial fragmentation of HOS cells after targeted PDT. The scale bars represent 10 µm. C, D CLSM imaging and FC analysis of the production of ROS levels in HOS cells (stained with DCFH-DA) after different treatments. The scale bars represent 100 µm. (The data are presented as the mean ± SD values; n = 3, *p < 0.05, **p < 0.01.) E The ATP content in HOS cells after different treatments (the data are presented as the mean ± SD values; n = 3, ***p < 0.001)
