Abstract
Paper describes the doping of hydroxyapatite (HAp) with three different metal ions Mg2+, Ag+ and Zn2+ for enhancing the biocompatibility of HAp. Samples morphology reveals an increase in grain size and the presence of rod-like structures. Tri dopants cause the crystallite size and cell volume to decrease. The sample was found to become harder. Rate of corrosion improved by 14 % as studied in the Ringer's solution. The dielectric studies confirmed that the samples were conducting in nature due to the presence of PVA in the sample. Lesser number of pores was observed for the composite sample which implied improved hardness of those samples. Clotting behaviour decreased after doping due to the increased conducting behaviour after the doping. To test the antibacterial activity, two strains of the bacteria E. coli and S. aureus were used. 10 wt% PVA-Ag/Mg/Zn-HAp demonstrated higher efficacy against both the strains of the bacteria.
