|a Microbiota-based therapeutics offer innovative strategies to treat inflammatory bowel diseases (IBDs). However, the poor clinical outcome so far and the limited flexibility of the bacterial approach call for improvement. Inspired by the health benefits of probiotics in alleviating symptoms of bowel diseases, bioartificial probiotics are designed to restore the intestinal microenvironment in colitis by regulating redox balance, immune responses, and the gut microbiome. The bioartificial probiotic comprises two components: an E. coli Nissle 1917-derived membrane (EM) as the surface and the biodegradable diselenide-bridged mesoporous silica nanoparticles (SeM) as the core. When orally administered, the probiotic-inspired nanomedicine (SeMEM) adheres strongly to the mucus layer and restored intestinal redox balance and immune regulation homeostasis in a murine model of acute colitis induced by dextran sodium sulfate. In addition, the respective properties of the EM and SeM synergistically alter the gut microbiome to a favorable state by increasing the bacterial diversity and shifting the microbiome profile to an anti-inflammatory phenotype. This work suggests a safe and effective nanomedicine that can restore intestinal homeostasis for IBDs therapy
