Heat operation for synthesis of calcinated hydroxyapatite and loading silver nanoparticles on it

The bioceramics, calcium hydroxyapatite (HAP), is a material which is biocompatible to the human body and is well suited to be used in hyperthermia applications for the treatment of bone cancer. We synthesis hydroxyapatite in modified synthetic body fluid (SBF) solutions at 37°C and pH of 7.4 using novel chemical precipitation technique. Then after heat operation, on filtered precipitated result HA were produced. For loading the silver nanoparticles (Ag NPs) on the hydroxyapatite we use AgNO3 solution. And for reducing Ag+ ions apply sodium bohrhydrate solution. The formations of the silver nanoparticles on the HAP structure were confirmed by X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM). TEM image show the nanostructure of silver particles, being formed on hydroxyapatite texture
