Dual-functionalized photoactive colloids have a variety of potential applications including photocatalysis, colloidal robotics, and the building of more complex devices. The purpose of this paper is to describe a simple and comprehensive method for fabricating functional colloidal assemblies using a photoresponsive material by manipulating interparticle forces, applying surface modifications, and developing assembly techniques. This is demonstrated using a gold-silicon-silver triplet structure of approximately 5-10 µm.
