Fabrication and mechanism illustration of CPIP@EV–CM for amplifying tumor immunotherapies. a Assembly synthesis process of Pt-Pta/Por (CPIP). b Schematic illustration of the membrane derived from EV and CM fusion. The resulting hybrid membrane camouflaged with CPIP to produce CPIP@EV–CM. c The EV–CM hybrid membrane inhibited the occurrence of melanoma. d Synergistic sonodynamic/chemodynamic/immunotherapy for melanoma.
