The eradication of drug-resistant microbial biofilms remains an unresolved global health challenge. Small-scale robotics are providing innovative therapeutic and diagnostic approaches with high precision efficacy. These rapidly moving from proof-of-concept studies to translational biomedical applications using ex vivo, animal, clinical models. Here, we discuss the fundamental aspects how microrobots target infection sites disrupt structural functional traits their antimicrobial resistance mechanisms. We emphasize current mechanochemical disruption on-site drug delivery that supported by in vivo models preclinical testing, while also highlighting diagnostics potential. translation challenges provide perspectives for development microrobotics combat biofilm infections biofouling humans.
