ABSTRACT
Biohybrid micro/nanorobots have demonstrated improved therapeutic outcomes for targeting and treating diseases in preclinical trials. However, in vivo applications remain challenging due to a lack of sufficient targeting. Based on evidence that immune cells play a role in the immune modulation in the tumor microenvironment, we developed M1 macrophage membrane-coated magnetic photothermal nanocomplexes (MPN) for photoacoustic (PA) imaging-guided tumor therapy. The MPN were able to inherit the protein from the original macrophage cells and exert a targeted immunosuppression role. Integrating black phosphorus quantum dots and DOX also greatly enhanced reactive oxygen species generation and chemo-phototherapy efficacy. The results suggest that the MPN can be employed as an excellent tumor immunotargeting nanorobotic platform for modulating the tumor microenvironment under PA imaging and magnetic guidance and, thus, exert synergistic therapeutic efficacies.
