Schematic diagram showing the design of charge switchable NPs for delivery of vancomycin to bacterial cells. b) Zeta potential of NPs, ZP of PLGA-PLH-PEG increases with decreasing pH. c) Minimum inhibitory concentrations (MICs) of vancomycin against S. aureus in different conditions. Significant loss of drug activity observed in PLGA-PEG (Vanco) and free Vanco. Reproduced from reference 46 with permission from American Chemical Society, Copyright © 2012.
