PSBTBT-Ce6@Rhod NPs nanoplatform for precise PTT/PDT co-therapy. A Schematic illustration of PLD-activatable tumor image and PTT/PDT co-therapy. B Singlet oxygen level indicated by DCF-DA staining in MCF-7 cells that incubated with free Ce6, PSBTBT NPs, and PSBTBT-Ce6@Rhod NPs. Green color represents fluorescence of DCF-DA. C IR thermal images of tumor-bearing mice in different groups after NIR laser irradiation for 10 min. D Tumor temperature changes treated with saline, PSBTBT-Ce6@Rhod NPs and PSBTBT NPs under laser irradiation. E Thermal images and F quantitative temperature change curve of PSBTBT-Ce6@Rhod NPs in PBS buffer solution [215]
