Nanofabricated Bacterial Cell Walls with Intrinsic Peroxidase‐Mimicking and Sonodynamic Activities for Cancer Combination Treatment

and consume the reduced glutathione (GSH), and thus greatly boost their own sonodynamic performance upon ultrasonic irradiation. Both in vitro and in vivo, DOX@CWV efficiently inhibited cancer growth by combining SDT and chemotherapy, and also exerted synergistic anticancer immune effects of bacterial immunotherapy and SDT. In summary, the findings not only contribute a promising bacterial therapeutic agent but also provide a combination strategy for clinical cancer treatment.
