英文摘要 | Enhancing the lubrication property and bacterialresistance is extremely important for interventional biomedicalimplants to avoid soft tissue damage and biofilm formation. In this study, a zwitterionic phosphorylcholine coating (PMPC) was successfully developed to achieve surface functionalization of apolyurethane (PU)-based ureteral stent via subsurface"graftingfrom"photopolymerization. Typical surface characterizations suchas Fourier transform infrared spectroscopy, X-ray photoelectronspectroscopy, and surface wettability and morphology analysesexamined by scanning electron microscopy, atomic forcemicroscopy, and transmission electron microscopy demonstratedthat the phosphorylcholine polymer was grafted on the substratewith a thickness of 180 nm. Additionally, the tribological experiment performed by a universal material tester showed that thelubrication performance of PU-PMPC was significantly improved compared with that of PU. Thein vitroexperiments indicated thatthe PMPC coating was biocompatible and stably modified on the surface of the substrate with an excellent bacterial resistance rate of>90%. Furthermore, the result of thein vivoexperiment showed that the anti-encrustation performance of the surface-functionalizedureteral stent was better than that of the bare ureteral stent. The great enhancement in the lubrication, bacterial resistance, and anti-encrustation properties of the phosphorylcholine coating was thought to be due to the hydration effects of the zwitterionic charges. In summary, the bioinspired zwitterionic phosphorylcholine coating developed herein achieved significantly improved lubrication, bacterial resistance, and anti-encrustation performances and could be used as a convenient approach for surface functionalization of interventional biomedical implants |
