　　The bacterial colonization and adhesion on biomedical implants and subsequent biofilm formation often lead to serious bacterial infections.The sudden rise in antibiotic-resistant bacterial infections is the main reason for life-threatening infection diseases.Currently,intravenous antibiotic injection is the most practicing way to deal with implant-associated infections.However,the occurrence of antibiotic-resistant bacteria has become more dangerous by misuse and taking a huge amount of antibiot...
