Synthesis and Characterization Silver–Tricalcium Phosphate (TCP) Nanoparticle using Avocado Leaf Extract (Percea americana)

Abstract

The silver-TCP nanoparticle synthesis was carried out in this study. Silver nanoparticles are made by reducing silver nitrate solution using avocado leaf extract as a bioreactor. Tricalcium Phosphate (TCP) is dipped into silver nanoparticles to form a silver-tricalcium phosphate composite. The UV-Vis analysis shows the formation of silver nanoparticle absorption peaks at a length of 445-446 nm, which is a typical peak of silver nanoparticles caused by the Surface Plasmon Resonance (SPR) phenomenon. X-Ray Diffraction (XRD) shows that the TCP crystal size is 64 nm and the size of the Silver Crystal in the composite is 46 nm. The results of Scanning Electron Microscopy (SEM) show silver particles distributed on the surface of TCP particles.
