Photothermally Responsive Conjugated Polymeric Singlet Oxygen Carrier for Phase Change-Controlled and Sustainable Phototherapy for Hypoxic Tumor
(a) Melting point change of PCM with different Hex/OA mass ratios. (b) Photothermal images of CP1-NCs. (c) Temperature elevation of CP1-NCs at different levels under 690 nm light irradiation at 0.5 W cm-2 for 6 min. TEM of CP1-NCs, (d) before, and (e) after irradiation for 6 min. Scale bars: 200 nm. (f) of DPBF under various temperatures in the mixture solution of CP1-NCs and DBPF. (g) Schematic illustration of photothermal-induced release of CP1-NCs.
