The Production of Gold Nanoparticles via Chemical Reduction Methods and Their Antimicrobial Characteristics

Abstract

Due to their remarkable chemical and physical properties gold nanoparticles have demonstrated potential antibacterial efficacy in an attempt to address this problem. Many variations of these gold based nanostructures have been created. With an emphasis on a temperature of 60 C⁰, a number of experiments have been conducted to create stable gold nanoparticles utilizing chemical reducing agents such as sodium trinitrate. Scanning electron microscopy (FESEM) and ultraviolet spectroscopy were used to examine the resultant gold nanoparticles. These analyses yielded findings between 27.69 and 53.26 nm. The red gold nanoparticle solution's spectrum started at 530 nm. Although the forms and sizes of gold nanoparticles produced by various reactions vary, spheres are the most prevalent. The existence of FCC cubic gold was indicated by the four primary peaks in the gold nanoparticles' XRD pattern, which were located at (111), (200), (220), and (311).
