Green Synthesis of Psidium guajava Capped Hydroxyapatite Nanoparticles

The current research has been carried out in synthesis and characterization of hydroxyapatite nanoparticles of 26±5nm from Psidium guajava leaf extract with control over dimension and composition. The reaction occurs very rapidly as the formation of spherical nanoparticles almost completed within 30nm. The probable pathway of the green synthesis is suggested. Appearance, crystalline nature, size and shape of nanoparticles are understood by Scanning electron microscopy, Energy Dispersive X-Ray Analysis, Fourier-transform infrared spectroscopy and X-Ray diffraction techniques. Microwave-assisted route is selected for the synthesis of hydroxyapatite nanoparticles to carry out the reaction fast, suppress the enzymatic action and to keep the process environmentally clean and green
