ABSTRACT
Objective:
To construct an antibacterial peptide controlled release coating for percutaneous implant and to study its release and antibacterial properties.Methods:
TiO2 nanotube specimens were prepared by anodizing. PDLLA was used as the retarder and HHC-36 as the antibacterial peptide, PDLLA-HHC-36 were loaded on TiO2 nanotube surface by solvent-casting technology. The surface form of the specimens was observed under SEM. Sustained release was analyzed by the release curves and the antibacterial effect was examined with inhibition zone test.Results:
TiO2 nanotube specimens with 80-120 nm diameter were fabricated, the drug coating was observed under SEM. The drug loaded specimens showed 15 days sustained release in vitro and inhibition zone about 15 mm in diameter was found in the test for at least 10 days.Conclusion:
TiO2 nanotube specimens with PDLLA-HHC-36 controlled release coating has sustained-release and antibacterial properties.
