Bio-Fabrication of Nacre on Conventional Implant Materials
Nacreous coatings on orthopedic implants can be advantageous because of its robust mechanical properties, high biocompatibility, and ability to promote bone growth. The biofabrication of nacreous coatings on conventional orthopedic implant materials via biomineralization process from abalone shells was examined. The objective was to investigate the effect of different materials on nacreous coating growth. The coatings were characterized by SEM/EDS and XRD. It was found that different materials resulted in different surface morphologies and coating thicknesses, although the main mineral formed was aragonite. Calcium carbonate coating was formed on the entire surface of the poly (methyl methacrylate) and high density polyethylene implants and resulted in a thick coating, while the titanium implants showed thinner coating at the same growing period.
