Fabrication of polylysine based antibacterial coating for catheters by facile electrostatic interaction

Despite the development of advanced antibacterial biomedical materials, bacterial infection is still a serious problem for indwelling catheter because it usually induces severe complications. Hence, medical indwelling catheter with the capabilities of antibacterial activity, stability, biocompatibility is urgently needed. In this work, a water-insoluble antibacterial coating based on ε-Poly-ʟ-lysine (PL) was prepared via a facile electrostatic...
