Preparation and characterization of gold nanoparticles
Dec 01, 2019· 1. Introduction. Since the early 20th century, the synthesis of gold nanoparticles (AuNPs) has fascinated the scientific community due to their unique physiochemical and biological properties (Link and El-Sayed, 1999, Daniel and Astruc, 2004).It is because of these special properties that many research groups have attempted to use AuNPs to address societally important problems in
Synthesis And Characterization Of Gold Nanoparticles
By using Zeta-sizer, particle size and size distribution of synthesized gold nanoparticles were found . The synthesized gold nanoparticles were imaged by scanning electron microscope . 3.1 UV-VIS SPECTROPHOTOMETRY: For characterization of gold nanoparticles, there is an important aspect known as spectrophotometry .
A review on biogenic synthesis of gold nanoparticles
Dec 01, 2017· The characterization of these gold nanoparticles begins with a visual color change which works on the principle of surface Plasmon resonance (SPR). The color change occurs when the size of the particles increases, in the case of gold it is from deep red to purple.
