Silver nanoplates (SNPs) having different size were synthesized by a seed-mediated method. The seeds -silver nanoparticles with 4 – 6 nm diameters were synthesized first by reducing silver nitrate with sodium borohydride in the present of Trisodium Citrate and Hydrogen peroxide. Then these seeds were developed by continue reducing Ag\(^+\) ions with various amount of L-Ascorbic acid to form SNPs. Our analysis showed that the concentratrion of L-Ascorbic acid, a secondary reducing agent, played an important role to form SNPs. In addition, the size and in-plane dipole plasmon resonance wavelenght of silver nanoplates were increased when the concentration of added silver nitrate increased. The characterization of SNPs were studied by UV-Vis, FE-SEM, EDS and TEM methods.

It has been proven that HA coatings on implant materials treated with silver exhibited excellent antibacterial effects. Silver (Ag) ions were successfully incorporated into HA structure with the precipitation method. Although this method was pretty much suitable for the synthesis in powder form, it is not applicable to in-situ coating processes. The aim of the current study is to synthesize Ag ion incorporating HA via the decomposition of EDTA Chelate. For this reason, Ag doped crystalline-sodium and carbonate-containing HA solutions will be prepared using calcium-EDTA in a sodium phosphate solution, hydrogen peroxide and silver nitrate. As the source of Ag ions, silver nitrate was added into the solution in the desired proportions. Then, the samples were sintered at temperatures from 800oC to 1100oC and characterized with XRD and SEM.
