Schematic illustration of the fabrication of the injectable hydrogel system with excellent photo–heat transition capacity. This system was fabricated using a one-step synthesis method. Ti₃C₂ nanoparticles and thermosensitive Pluronic F127 were mixed to prepare the photothermal agent-embedded hydrogel system. The system can form in situ gel in tumor tissue through sol–gel transition and prolong the retention of Ti₃C₂ nanoparticles. Using near-infrared laser irradiation, repeated treatments can be achieved with a single injection.
