摘要：

An innovative method for stabilization of gold nanoparticles (GNPs) in the aqueous solution using natural plant extract from Aloe vera is presented in this work. A detailed spectroscopic analysis of the GNPs after the interaction of Aloe vera gel in different molar ratios (1:50 and 1:150) and pH values (5.3 and 7.4) reveals the excellent capping property and stabilizing nature of gel. Morphological feature as well as surface protection of GNP surfaces was confirmed by Field Emission Scanning Electron Microscopic (FE-SEM) analysis and Fourier Transform Infra-Red (FTIR) Spectroscopy respectively. It was found that higher ratios of GNPs and Gel lead to more stabilization of nanoparticles. Flocculation parameter was found to be less with increasing ratios at both the pH values indicating the stability of nanoparticles. (c) 2015 Published by Elsevier B.V.
