Assembly of nanoparticles into useful one, two or three-dimensional structures is a critical aspect to fully appreciate their utility. For example, self assembly, or bottom-up manufacturing, could be used to make microelectronic devices, in the best case, by randomly depositing all the nanoscopic components onto a substrate then activating their assembly into the working device. We show that by using a combination of entropy, surface energy (enthalpy) and metastable trapping through van der Waals forces we are able to assemble nanoparticles in one, two or three-dimensions within polymer films as a first step towards realizing useful devices.
