Inflammatory bowel disease involves excess reactive oxygen species (ROS) and hydrogen sulfide (H2S) at inflammatory sites. Nanozyme-mediated ROS H2S scavenging therapy is promising for colitis treatment. Here, we synthesized a multiple Cu5.4O nanoparticle first explored its capacity. Chitosan oligosaccharide modified with alpha-lipoic acid was coated on the nanoparticles to further enhance Furthermore, calcium alginate surface develop an oral nanoplatform (Cu5.4O@SAG) possessing dual-pH/H2S-responsive release characteristics. Importantly, Cu5.4O@SAG exhibited enrichment colonic inflammation site relieved index, containing recovery of colon length, spleen liver body weight, as well cell infiltration. In vivo in vitro experiments revealed dual capacities nanoplatform. Additionally, regulated tight junctions, mucus layers, gut microbiota, which accompanied by downregulation cytokines. Notably, also had excellent biocompatibility. conclusion, this multiple-scavenging nanozyme platform provides new safe paradigm development nanozymes
