A CHEMOMETRIC APPROACH TO THE INFLUENCE OF THE SYNTHESIS PARAMETERS ON THE OPTICAL RESPONSE OF GOLD NANOPARTICLES AND STUDY OF THEIR ELECTROPHORETIC DEPOSITION ON SILICON
This study describes gold nanoparticle synthesis in an aqueous solution by reducing tetrachloroauric acid (HAuCl4), using sodium citrate as a reducing agent. Synthesis was optimized through an experimental design, and particle characterization was obtained through UV-Vis spectroscopy. In a first sta...
