Nanotech Malaysia 2018 Green sonochemical synthesis of gold nanoparticles using palm oil leaves extracts Adamu Ibrahim Usman a,c , Azlan Abdul Aziz b *, and Osama Abu Noqta a a School of Physics University Sains Malaysia, 11800, Pulau Pinang, Malaysia b Institutes for Research in Molecular Medicine , USM, 11800, Pulau Pinang, Malaysia c Department of Physics, Federal University Kashere, Nigeria Abstract Synthesis of nanoparticles using various stabilizing agents is one of the major focuses of scientific community now a days. One pot green synthesis of gold nanoparticles (AuNPs) was successfully achieved using palm oil leaves extracts as stabilizing agent and ultrasound radiation as reducing agent. The effects of concentration of palm oil leaves extracts was investigated. The functional groups such as OH – , CO – stretch, NH – stretching and other function groups were found to be responsible for stabilizing the AuNPs. Dynamic light scattering (DLS) was employed to measure the average particles sizes and the distribution of the as-synthesized AuNPs. The average particles size were found to be between 92.37 to 112.3 nm for particles size using 2 % and 5 % of POLE respectively. The morphology of the as-synthesized AuNPs was investigated using EFTEM. The XRD patterns display the peaks of face centered cubic crystal structures at (111), (200), (220), (311) and (222). © 2018 Elsevier Ltd. All rights reserved.

Introduction Phytochemicals are the corner stone that build the relationship between nanotechnology and green chemistry in the synthesis process [1], It is generally know that the role play by phytochemicals is persuading various kinds of chemicals manipulation in biological system. Green Nano revolution will be successful if nanotechnology and green model are combined to make non – toxic nanoparticles for pharmaceutical and biomedical applications [2].
