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.

Abstract: According to the present invention, an ultra-fast method for preparing an organic/inorganic thin film by using self-diffusion effects comprises the steps of: forming a solution by dissolving one or more organic/inorganic materials in a solvent; forming an organic/inorganic thin film by supplying the formed solution onto a liquid substrate; and transferring the formed thin film to a substrate, wherein the step of forming an organic/inorganic thin film forms a thin film on the liquid substrate from the organic/inorganic materials through the occurrence of a self-diffusion phenomenon caused by a difference in surface tension between the liquid substrate and the solution, and through the occurrence of the evaporation of the solvent and the dissolution process of the solvent to the liquid substrate.

Abstract: A method for synthesizing enzyme-catalyzed polymers using the Langmuir-Blodgett technique. In one embodiment, the process comprises spreading one or more enzyme-polymerizable monomers on a water-miscible solvent. The monomers are sufficiently surface active that they align themselves on the air-solvent interface. Next, pressure is applied to the interface to form a monolayer made up of the monomers. An enzyme is then introduced into the solvent, causing polymerization of the monomers in the monolayer. The polymeric monolayers produced by the present method are easier to process and have reduced cross-linking and branching as compared to similar polymers produced in bulk by enzyme-catalyzed reactions.

Abstract: The present disclosure generally pertains to methods of preparing a well-ordered nanoparticle coating on a substrate. A nanoparticle solution having nanoparticles in a solvent is deposited on a sub-phase of a denser, immiscible liquid. A constrained area on the top surface of the sub-phase is provided, where nanoparticle solution spreading is physically limited and the nanoparticles spontaneously form a uniformly ordered monolayer on the sub-phase within the constrained area. Notably, no compression of the nanoparticle film occurs after the spreading phase in order to form the monolayer. After the monolayer is formed, a substrate is placed into contact with the monolayer and coated with a well-ordered nanoparticle coating.
