New switchable hydrogels are developed. Under acidic conditions, hydrogels undergo self‐cyclization and can catch and kill bacteria. Under neutral/basic conditions, hydrogels undergo ring‐opening and can release killed bacterial cells and resist protein adsorption and bacterial attachment. Smart hydrogels also show a dramatically improved mechanical property, which is highly desired for biomedical applications.
