The current state of nanoparticles fabrication via polymer or solid state means is limited by the instability of the formed nanoparticles against self-aggregation and the ability to produce monodispersed nanoparticles on the macro-scale. Hence, motivation for this project is to construct a solid state nanoreactor that uses multifunctional reduction methods (chemical reduction and photoreduction) to produce technologically relevant monometallic and multimetallic nanoparticles with controllable shapes and sizes and with specific designed cores and shell compositions at the macroscale “gram scale”. In particular, this design will take advantage of flow rates, reactant concentrations, and host media “polymers” to control the growth nucleation, shape, and size of CuNi, CoPt, and CuNiCo particles. The resulting morphologies and structures of the formed nanoparticles will be characterized by SEM, TEM, and XPS. Furthermore, future tests will be conducted to establish the influence of the particle’s composition, shape and structure on its bioaccumulation in the environment, solubility in water and in various buffer solutions.
