Abstract
Comprehensive SummaryThe intensive use of antibiotics intensifies the development of bacterial resistance, which has become a serious problem globally. Methicillin‐resistant Staphylococcus aureus (MRSA) has resulted in significant morbidity and mortality. Therefore, it is an urgent need to develop new antimicrobial drugs and administration methods. Herein, we report a dual functional diblock copolymer PLL20‐b‐PBLG20, which was prepared by superfast and water‐insensitive polymerization on N‐carboxyanhydrides (NCA) initiated by tetraalkylammonium carboxylate. In addition to direct antimicrobial activity, PLL20‐b‐PBLG20 also exerts a synergistic bactericidal effect against MRSA with curcumin, a plant extract with antibacterial property. Moreover, PLL20‐b‐PBLG20 successfully encapsulates curcumin to form nanoparticles via self‐assembly. The combination of dual functional PLL20‐b‐PBLG20 and curcumin holds promise in combating MRSA infections.
