Shape-dependent magnetic-driven microrobots for biofilm-eradicating medical device disinfection through mechanical and chemical bactericidal action
Biomedical device-associated infections are a primary cause of clinical treatment failure, with persistent biofilm infections in the intricate architectures of medical devices further compounding the issue. In this work, we developed magnetite microrobots (Fe3O4 MRs) with various geometries, including cubic, spherical, and fusiform shapes, which integrate magnetically driven mechano-bactericidal performance with peroxidase (POD)-like catalytic activity …
