Abstract

The invention discloses a preparation method of magnetic beads of dendritic molecular imprinting polymer on a surface of estrogenic nano silica gel. The preparation method comprises the following steps of: carrying out cross-over study on a magnetic nano material and dendritic polymer study technology, a dummy template technology and a surface molecular-imprinted technology and then carrying out dendritic molecular imprinting design of the surface of the magnetic nano silica gel on low-abundance environmental estrogens; by means of the advantage of nano construction with rich functional groups provided by the dendritic molecules, preparing a controllable, ordered and dense molecular imprinting nuclear shell on the surface of a carrier material and synthesizing a new molecular imprinting material with high efficiency and strong magnetism. According to the preparation method, the problem of low efficiency of surface molecular imprinting is solved and the fast and sensitive detection of residual estrogens in foods and environments is realized.

Description

technical field

[0001] The invention belongs to the technical field of new materials, and in particular relates to a preparation method of dendritic molecular imprinted polymer magnetic beads on the surface of estrogen nano-silica gel. Background technique

[0002] At present, food safety has become a global focus, especially in my country. Such as the abuse of adrenergic receptor agonists, estrogens and antibiotics in the breeding industry, and the abuse of pesticides in the agricultural industry, the problem of harmful residues in food has become increasingly serious. Since humans are at the top of the food chain, they have become a gathering place for pollutants. Many residual drugs are extremely harmful to human health and ecological environment at very low levels. For example, environmental estrogens (EES) mostly at ppt-ppb or lower levels will have a great impact on organisms. The International Codex Alimentarius Commission (CAC), the European Union, the United State...
