The advance of antibodies targeting tumor necrosis factor\u2010alpha and interleukin\u201012\/23, e.g., infliximab (IFX) and ustekinumab (UTK), has greatly improved the clinical treatments. The current intravenous dosing scheme, however, yields partial responses with potentially severe systemic side effects. Here, we report that oral prebiotic polysaccharide hydrogels based on inulin and alginate\u2010dopamine conjugate (predaGel) mediating efficient and sustained colon antibody delivery and reactive oxygen species (ROS)\u00a0scavenging effectively alleviate IBD. predaGel with pH and enzyme dual responsiveness\u00a0is stable in the stomach, adhesive to the intestine, and slowly degrading in the colon, resulting in site\u2010specific and controlled release of IFX. The mucosal retention, ROS scavenging, and gut microbiota remodeling properties endowed by dopamine and inulin in predaGel not only prevent diarrhea and suppress oxidative stress but also prolong drug function and restore immune homeostasis. Intriguingly, oral administration of IFX and\/or UTK\u2010encapsulated predaGel cures IBD and restores colon function, offering an effective oral alternative to IFX injection. This oral prebiotic hydrogel strategy, with simplicity and multi\u2010functions, presents a potentially safer and better biologic therapy for IBD.<\/jats:p>","DOI":"10.1002\/advs.76425","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T14:35:41Z","timestamp":1783348541000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Oral
