Silver nanoparticles have unique physical, chemical, and optical properties that are used in a wide array of applications, such as chemical/optical sensing. For this study it has been determined that nanoparticles with a larger face geometry, or more faces, and sharper corners have a higher sensing ability, therefore are more ideal for optical sensing. To synthesize these nanoparticles with cubic or octahedron geometry, there are a few variables that can be analyzed. These variables include reducing agents, capping agents, and etching agents. Capping agents will be of focus in this research because of their ability to limit the size and shape of the nanoparticle during aggregation. The size, geometry, and composition of the nanoparticles are analyzed through UV/VIS and STEM-EDS with respect to different capping agents and different concentrations of capping agents.
