Synthesis of silver nanoparticles, influence of capping agents, and dependence on size and shape: A review

Abstract Silver nanoparticles have demonstrated a wide range of applications derived from shape and size control which is a crucial factor to improve antimicrobial, physical, and chemical properties. The use of different capping agents not only can control the material’s particle size, agglomeration, and morphology but also stability over time of nanostructures. Furthermore, the type of interaction of the capping agent on the surface of the nanoparticles influences the nanostructure formed. This article sought to present an overview of the shape-controlled synthesis and stability of silver nanoparticles by using various capping agents.
