Using a non-reducing sugar in the green synthesis of gold and silver nanoparticles by the chemical reduction method

Abstract

The use of more biocompatible and renewable chemical compounds to obtain metal nanoparticles with desired properties and characteristics becomes an alternative route for the reduction of environmental risks and to minimize the incompatibility of these structures when interacting with biological models for their possible application in the health area. The purpose of this research was focused on the use of sucrose, as a reducing agent for gold and silver nanoparticles using different volumes of sodium hydroxide. The nanoparticles obtained were characterized by UV-visible spectrometry, transmission electron microscopy TEM and Fourier transform infrared spectroscopy FTIR, which allowed to determine the surface plasmon resonance, experimental and theoretical particle sizes, morphology and structural changes in the reducing agent, as well as the influence of sodium hydroxide in the synthesis process. The results obtained confirm the generation of gold and silver nanoparticles by the previous formation of reducing sugars and oxidation of the functional group from glucose to salts of carboxylic acid.
