Anisotropic materials have a variety of unique properties and applications, including catalysis and directed assembly. In this work, the production of core-partial shell silver nanocube-copper oxide nanoparticles is the goal. To produce these particles, nanocubes are deposited onto polystyrene films, and embedded to a controlled depth. This allows for control over the exposed surface, the surface available for coating with copper oxide. These nanoparticles can be removed from the surface, allowing their in-solution properties to be probed. Several set-ups were tried, leading to the development of a promising final set-up. Each of the set-ups had different stirring rates, stability of the attached slide and production of bubbles, which interferes with the production of copper oxide shells. The produced morphologies varied for different order and rate of addition of precursors, allowing for control over the produced morphology by changing these parameters. With this method, core-partial shell particles can be successfully produced.
