Molecular decoys help overcome drug resistance

are surface proteins that prevent from getting a foothold in a by identifying and pumping them out of the cell. New research suggests that small pieces of those drugs could keep the efflux pumps busy and allow the antimicrobial drugs to reach a critical mass inside the cell.
