Study of Two Synthesized Methods of Gold Nanoparticles Synthesis Using Fresh Flowers Extracts of Clitoria ternatea

Abstract

In this research, the syntheses of AuNPs using the flowers extract of butterfly pea (Clitoria ternatea) were studied by two synthesized methods including 1) heating 2) microwave assisted extraction. C. ternatea extract (CT extract) was prepared using the microwave assisted extraction. The best condition for syntheses of AuNPs using CT extract were performed using microwave assisted extraction (1,000 watt for 3 min). The morphology of the synthesized AuNPs from microwave assisted extraction was investigated by transmission electron microscopy (TEM) and X-Ray diffraction analysis (XRD), respectively. The TEM image of synthesized AuNPs also showed that most nanoparticles were in a spherical shape and XRD pattern presented an intense peak at 2θ = 38.44°, 44.41°, 65.03° and 77.58°, respectively which correspond to face centered cubic structure with (111), (200), (220) and (311) plane.
