Bioynthesis of silver nanoparticles using Graptophyllum pictum leaves extracts

Abstract

Silver nanoparticles (AgNPs) have found significant application in industry especially in medical and catalysis field. Considerable attention has been made to synthesis AgNPSs via various routes. However, in recent years, focus have been shifted to synthesis AgNPs using more environmentally friendly route. Attempts to synthesis AgNPs by using plant extracts as potential complex reducing agent have found significant interest to date. Hence, this work will explore the feasibility to synthesis AgNPs by using locally available Graptophyllum pictum leaves (puding hitam). The extracts were evaluated on the their total phenolic content to shed potential insights on the mechanism prior AgNPs synthesis. The feasibility of the AgNPs were evaluated by using UV-Vis and Transmission electron microscopy (TEM). In conclusion, Graptophyllum pictum leaves (puding hitam) could be a viable alternative for the environmentally friendly synthesis of AgNPs.
