Trap, kill, and release: An antimicrobial cationic surface can effectively kill bacterial cells and switch to a nonfouling zwitterionic surface which releases dead microorganisms upon hydrolysis (see picture). This biocompatible nonfouling surface can prevent further attachment of proteins and microorganisms and the formation of a biofilm on the surface.
