Critical Research on Biological Synthesis and Characterization of Gold Nanoparticles (AuNPs), Using Plant Extracts

The objective of this current work was to carry out biological synthesis and characterization of gold nanoparticles ( AuNPs) using plant extracts using environmentally friendly technology: cactus (Opuntia sp.), onion (Allum sp.), pear (Pyrus sp.), coffee (Coffea sp.) and laurel (Laurus sp.), as reducing agents and stabilisers. Normal methodologies have been obtained. Maximum absorbance at 527-537 nm was determined by UVVisible spectrophotometry characterization, while transmission electron microscopy ( TEM) and atomic force microscopy ( AFM) reported that the biosynthesis of gold nanoparticles developed various shapes, including spheres, cubes, cones, cylinders and others, with a size of 5-100 nm depending on the extract used, so that the proposed method is used In addition, these AuNPs can be functionalized.
