Synthesis silver nanoparticles using trisodium citrate and development in analysis method

Abstract

Synthesis of silver nanoparticles (AgNPs) and analytical development of sylver nanoparticles has been done. AgNPs were making by chemical reduction method using trisodium citrate as a reducing agent. AgNPs was prepared with a variant of silver nitrate concentration, and stirring time to result in the best silver nanoparticles. AgNPs were characterized using Uv-vis Spectrophotometer, Particles Size analyzer (PSA), Transmission Electron Microscopy (TEM). AgNPs was applied as the colorimetric sensor of histamine. The histamine presence can induce the agregation of silver nanoparticles by a color change from yellow to brown.
