    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.
