Surface modification of titanium implants by ZIF-8@Levo/LBL coating for inhibition of bacterial-associated infection and enhancement of in vivo osseointegration

Bone implant-associated infection is one of the major concerns in orthopedics, and may even result in implant failure. To this end, we developed a strategy for the fabrication of an antibacterial coating on titanium (Ti) implants with pH-response to combat bacteria-mediated acidification of the local microenvironment. It includes three steps: first, we synthesized levofloxacin (Levo)-loaded zeolitic imidazolate framework-8 ([email protected])...
