Patent Title: Synthesis of shell-like molecularly imprinted polymer and application thereof for detecting persistent pesticides
Publication date: 2011
Publication number: CN102023156

Abstract: The invention discloses a novel approach to detecting pesticide residues and a method for detecting pesticide residues. The preparation of a molecularly imprinted polymer microsphere comprises the following steps of: preparing a mesoporous material; carrying out surface modification of the mesoporous material; synthesizing the surface molecularly imprinted polymer; and further making the molecularly imprinted polymer microsphere into a spherical shell structure. The method for detecting trace pesticide residues comprises the following steps of: putting the polymer in a prepared pillar for making a flowing cell; and then accessing the flowing cell in a flow path for detecting chemiluminescence signal strength. The molecularly imprinted polymer has strong specificity and high sensibility, can be put in the pillar and then is accessed in the flow path for detecting the chemiluminescence signal strength to achieve a mug level; the method only takes 3-5minutes to complete a basic detection process; and the cost is low. The method for detecting pesticide residues with the polymer is fast and simple to operate, and automatically completed and record reaction and results by using an instrument.
