Abstract

The present invention provides a fluorescent probe sensor, a method for making the same and a method for detecting fumonisins. The fluorescent probe sensor integrates a cationic surfactant and a fluorescent probe molecule, and has the advantages of simple preparation, easy operation, high sensitivity, good selectivity, and real-time online detection. Fluorescence sensor was used to detect fumonisins. Considering the excellent water solubility of fumonisins and the multiple carboxyl groups in the molecular structure, the direct quantitative analysis of FB1 in aqueous solution was realized, that is, no derivatization was required. It does not need to be chemically decomposed, and the detection sensitivity is high.

Description

technical field [0001] The invention relates to the field of display, in particular to a fluorescent probe sensor, a method for making the same and a method for detecting fumonisins. Background technique [0002] Fumonisins are water-soluble secondary metabolites produced by the reproduction of Fusarium moniliforme under certain temperature and humidity conditions. The structure is a straight chain composed of 19 or 20 carbon atoms, and various carboxyl groups, hydroxyl groups and ester bonds are distributed on both sides of the skeleton, which mainly pollutes corn, rice, wheat and other grains and their products. At present, there are 11 kinds of fumonisins, including FA1, FA2, FB1, FB2, FB3, FB4, FC1, FC2, FC3, and FC4, among which FB1 is the main component. Pure fumonisin is white or light yellow needle-like hygroscopic powder, easily soluble in water and polar solvents such as acetonitrile and methanol; it has no UV-absorbing groups and fluorescent properties; fumonisin...
