Abstract

The invention relates to a preparation method and application of a Mn-doped ZnS quantum dot surface imprinted fluorescent probe, which belongs to the technical field of environmental functional material preparation; the invention utilizes a free radical polymerization method to synthesize a pseudo-template of a molecularly imprinted polymer using propionamide, Methacrylic acid (MAA) was used as functional monomer, Mn-doped ZnS quantum dot graphene oxide (Mn:ZnS@GO) was used as matrix material, ethylene glycol dimethacrylate (EGDMA) was used as cross-linking agent, azobis Isobutyronitrile (AIBN) is an initiator, and N,N-dimethylformamide (DMF) is a solvent to synthesize a surface molecularly imprinted fluorescent probe, which is used to enrich and detect acrylamide in food; the method of the present invention The prepared fluorescent probe not only embodies the advantages of surface molecular imprinting, avoids too deep embedding of molecularly imprinted polymer template molecules prepared by traditional methods, improves the recognition efficiency and binding speed, but also takes into account the high luminous efficiency and Fast fluorescence decay and other advantages improve the detection rate and sensitivity.

Description

technical field

[0001] The invention relates to a preparation method and application of a Mn-doped ZnS quantum dot surface imprinted fluorescent probe, in particular to a preparation method of a fluorescent acrylamide virtual molecular imprinted polymer based on Mn-doped ZnS quantum dots on the surface of graphene oxide and applications, belonging to the technical field of preparation of environmental functional materials. Background technique

[0002] Acrylamide is a water-soluble neurotoxic substance that is carcinogenic to rodents. At present, some high-carbohydrate foods have been found to produce different levels of acrylamide after high-temperature cooking such as frying, roasting, and frying. And its content increases with the increase of processing temperature, which is a potential hazard to human health. In addition, polyacrylamide prepared by polymerization of acrylamide can be added to water as a flocculant to absorb and remove impurities in water, but a very sma...
