Notes:
In this experiment, un-dried silver-hydroxyapatite-titania nanoparticles slurry was used tomake membrane with Polyamide-66 by co-polymerization method. The morphology, chemicalcomponents and structures of the membrane were characterized by AAS, XRD, SEM and EDX. S.aureus, E. eoli, P.gingivalis, F.nucleatum and S.mutans were utilized to test the antibacterial effect.XRD results demonstrated that the membrane have characteristic diffraction peaks of pure HA. Ahomogeneous distribution of the Ca, P, Ti, and Ag element in the membrane was confirmed byEDX. Both surface and section showed porous structure which was confirmed by SEM and theholes size was average 20-30μm. The bacteria assay reflects to the antibacterial effect, 56.31 % ofS. aureus and 50.10 % of E. eoli were killed after 24 hours incubation. However, 91.84 % of P.gingivalis, 90.64 % of F. nucleatum and 90.49 % of S. mutans were killed and pictures of SEMshowed obviously fewer cells on the surface. So the nanocomposite membrane could be one of thebioactive materials with antibacterial properties for oral GBR technique
