Abstract: Gold nanoparticles are emerging as a novel platform that could simultaneously be utilized for both, cancer targeted drug delivery and imaging, commonly referred to as theranostic application. The present research work includes synthesis of gold nanoparticles using different reducing agents in various concentrations. Gold nanoparticles were prepared by chemical reduction method. A prepared gold nanoparticle was evaluated for particle size, zeta potential, poly dispersity index and UV visible spectrophotometry. Experimental data showed that The size of Gold nanoparticles varies as the concentration and type of reducing agent changes. Small size of gold nanoparticles was obtained with 1% trisodium citrate (24.20 nm) which was used as a reducing agent as well as stabilizing agent.
