Ag doped Hydroxyapatites (Ag-HAp) was prepared through either ion exchange orcoprecipitation to compare the durability of antimicrobial effect. In case of ion exchanged Ag-HAp,the microbials reproliferated after 100 h, in spite of the rapid reduction of E.Coli during the initialmoment. On the contrary, coprecipitated Ag-HAp effectively suppressed the reproliferation until1000 h. The difference in durability depending on synthesis route was analysed with respect to theamount of silver released at each interval. In case of ion exchanged Ag-HAp, more than 60% ofoverall silver was released during initial 10 minitues. On the contrary, coprecipitated Ag-HApreleased less than 40% of overall silver during the same period, meaning the comparatively uniformrelease behavior
