Cerium oxide for detecting hydrogen peroxide having a mesoporous structure a method for producing the same and a biosensor for detecting hydrogen peroxide comprising the same

摘要

The present invention relates to a cerium oxide for detecting hydrogen peroxide having a mesoporous structure, a manufacturing method thereof, and a biosensor for detecting hydrogen peroxide containing the same. The cerium oxide for hydrogen peroxide detection provided by the present invention has a larger pore size than the existing cerium oxide, and can easily carry enzyme molecules that react to produce hydrogen peroxide, such as glucose oxidase, and has a small particle size to transfer material. Is advantageous to In addition, due to the small crystalline size, the proportion of cerium trivalent ions involved in the color development action is high, so it shows a high activity against hydrogen peroxide compared to the existing cerium oxide, and shows a markedly improved color development. In addition, compared to other organic enzymes, it has excellent stability and is inexpensive, and does not require a color development substrate, so it is possible to economically and efficiently produce a color biosensor using this.
