Abstract

The present disclosure is directed to methods for preparing nanoparticle monolayers on a sub-phase by controlling the spreading rate of the nanoparticles. The nanoparticles are first prepared in a nanoparticle solution at a predetermined concentration with a solvent. The sub-phase solution is prepared to have a density and viscosity compatible with the desired spreading rate. Additives, such as glycerol, are used to alter the density of the sub-phase solution. A volume of nanoparticle solution is deposited on the surface of the sub-phase solution and allowed to spread in a controlled manner on the unconstrained surface, forming a uniform nanoparticle monolayer. A substrate is then placed in contact with the nanoparticle monolayer to form a uniform nanoparticle coating on the surface of the substrate.
