Abstract: Objective To prepare porous titanium surface loaded with funme peptide (FP) and explore its biocompatibility and antibacterial properties. Methods The sandblast and acid-etching (SLA) titanium was set as the control group, and the FP was loaded on the SLA titanium by alkali heating and silanization treatment. Three experimental groups were set up according to different concentrations of FP, and the surface elements of each group were analyzed. MC3T3-E1 cells were inoculated on the surface of each sample to investigate their biocompatibility. Staphylococcus aureus was inoculated on the surface of each group to detect their antibacterial property. Results All the experimental groups were silanized successfully, and FP molecule adhered stably on the surface of silanized titanium. Compared with SLA titanium, titanium in experimental groups had significant antibacterial performance, and the 5 mg/mL group was better. Meanwhile, it had good biocompatibility and could significantly up-regulate the adhesion and proliferation of MC3T3-E1 cells. Conclusion The porous titanium surface of FP has good biocompatibility and antibacterial property.
