Magnetite Micro/Nanorobots for Efficient Targeted Alleviation of Inflammatory Bowel Disease

Year: 2025

Type: article

Abstract: Millions of people worldwide have inflammatory bowel disease (IBD). Self-driven micro/nanorobots (MNRs) are efficient in the treatment of IBD. However, their lack of controllability regarding direction of motion in the organism and their inability to achieve continuous navigation limits their further application. In this study, polydopamine is wrapped around the magnetite surface, loaded with an anti-inflammatory drug resveratrol, and wrapped with pH-responsive sodium alginate to obtain magnetic MNRs. MNRs can be driven by magnetic fields to achieve directional movement and targeted transportation. In addition, MNRs can effectively remove reactive oxygen species from the inflammation site, repair intestinal damage, inhibit the cellular pathway of pro-inflammatory factors, such as MAPK and NF-κB pathways, and restore intestinal flora, thereby relieving IBDs. MNRs are safe and effective for in vivo treatment of IBD and have proven to be a promising therapeutic platform. This MNRs therapeutic strategy provides new insights into comprehensive IBD therapy.
