Abstract:
Based on hydroxyapatite (HAP), a kind of antimicrobial ceramic, i.e. hydroxyapatite loading Ag+ ions (HAP-Ag), is prepared in a wet chemical process with the addition of AgNO3. The X-ray diffraction analysis shows that the HAP-Ag is mainly composed of nitrate-apatite, which is formed by the substitution of Ca2+ with Ag+. The antimicrobial effects of the HAP-Ag and its resistibility against the acrobic Escherichia coli and Staphylococcus aureus are tested respectively through the spread plate method. The results show that HAP-Ag is capable of inhibiting the growths of E.coli and S.aureus.
