Bioinspired antibacterial microrobots derived from mammalian cells for biofilm disruption

Abstract

This manuscript reports bioinspired antibacterial microrobots for biofilm disruption and bacterial killing. Cell-derived magnetic microrobots (MMCs) have been prepared via polymer-assisted cell metallization, precisely preserving the original cell morphology. When decorated with Fe₃O₄ nanoparticles, MMCs mechanically disrupt biofilms through structural interactions and dramatically promote the bactericidal performance of H₂O₂.
