Abstract The other functions of bacterial membrane vesicles (BMVs) except serving as immune adjuvants and vaccine platforms are yet to be further explored. This study investigates the photothermal properties Rhodobacter sphaeroides‐derived BMVs (RMVs) beyond their immunostimulatory properties. A multifunctional nano‐biohybrid, termed CuM@RR, is constructed by encapsulating Cu‐based metal–organic framework (CuM) nanoparticles into DSPE‐PEG 2000 ‐RGD‐functionalized RMVs, leveraging functionalization cargo capacity BMVs. ‐RGD modification facilitates targeted delivery CuM@RR tumor sites. CuM core within decomposes in acid microenvironment, releasing Cu 2+ inducing cell cuproptosis. Under 808 nm near‐infrared irradiation, effect‐induced apoptosis synergizes with copper ions overload‐induced cuproptosis, causing irreversible mitochondrial damage cells triggering strong immunogenic death (ICD). released damage‐associated molecular patterns (DAMPs) tumor‐associated antigens (TAAs) during ICD, along inherent immunoadjuvant elicit robust anti‐tumor responses. In vivo experiments confirm that significantly suppresses growth prevents rechallenge without obvious systemic toxicity under synergistic effects therapy, immunotherapy, suggesting great potential this nano‐biohybrid developing safe effective multi‐therapeutic strategies.
