Schematic illustration of the fabrication A) of nano‐Pt/VP@MLipo and B) chemophototherapy performance in tumors. 1) Lipid and VP was dispersed in organic solvent (light yellow), and nano‐Pt was introduced in the water (light blue). 2) The mixture was sonicated to from an emulsion. 3) Organic solvent was evaporated until the gel‐like state was disappeared. 4) PBS addition led to the formation of liposomes containing nano‐Pt in the water cavity and VP in the lipid bilayer. Mφ cell membrane (CM) vesicles were then added for follow‐up hybridization. 5) The mixture was then subjected to freeze–thaw cycles and extrusion to generate the final biomimetic nano‐Pt/VP@MLipo prior to removal of unentrapped components.
