摘要:
Surface-modified microparticles and methods of making and using such particles are disclosed. The surface modified microparticles include a preformed or core microparticle that contains at least one active agent. The outer surface of the preformed or core microparticle carries a net surface charge. A monolayer is associated with the outer surface of the preformed or core microparticle. The monolayer includes at least one charged compound that has a charge that is different from the net surface charge of the preformed or core microparticle,

Stable colloid nanoparticles comprising poorly soluble drugs are disclosed, as well as methods of making and methods of using such nanoparticles, e.g., as therapeutics and diagnostics.
摘要:
Multiple layered functional thin films fixed on a solid support are provided which comprise multiple layers of functional molecules (such as enzymes and other proteins, pigments and dyes) admixed with polymer ions in combination with multiple layers of polymer ions without the functional molecules. The films are prepared by immersing a solid support having an electric charge in an admixed polymer ion-functional molecule solution having a net electric charge opposite to that of the solid support followed by immersing the solid support in a polymer ion solution having a net electric charge opposite to that of the admixed polymer ion-functional molecule solution, and repeating at least once the immersings of the solid support in the solutions. Alternatively, the films are prepared by immersing the solid support in a polymer ion solution having a net electric charge opposite to that of the solid support followed by immersing the solid support in an admixed polymer ion-functional molecule solution having a net electric charge opposite to that of the polymer ion solution, and repeating at least once the immersings of the solid support in the solutions.
摘要:
A method for the preparation of an immobilized protein ultrathin film reactor by immersing a solid support alternately into an aqueous solution of protein, and into an aqueous solution of polyion charged oppositely to said protein and preparing a structurally controlled ultrathin film of mono- or multi- protein layers on a said solid support with precision at molecular level. And a method for chemical reaction of a substrate by preparing an immobilized protein ultrathin film reactor composed of multiple layers of protein on a solid support by above mentioned method, and initiating a chemical change of the substrate molecules using obtained immobilized protein ultrathin film reactor.

摘要:
A method of patterning self-assembled thin films, including forming a photoresist layer on a substrate and then patterning and etching the photoresist layer. In combination with the etched photoresist layer, a self-assembled layer is formed on the substrate using LbL self-assembly.
