Preparation method and application of fluorescence sensor
The invention discloses a preparation method and application of a fluorescent sensor, and belongs to the technical field of fluorescent sensing materials. Organic fluorescent molecules are loaded into channels of mesoporous silica in a physical embedding mode, and then silanized light-emitting quantum dots are grafted to the surface of the mesoporous silica in a covalent bond mode. The fluorescent property and excellent water solubility of the light-emitting quantum dots are maintained, leakage of organic fluorescent molecules is effectively prevented, low cytotoxicity and protection effect of mesoporous silica are combined, and the characteristics of specific fluorescent property and the like of the organic fluorescent molecules to H2O2 are exerted. And the ratio fluorescent nano sensor with good practical application value is obtained..
