Patent Title: Electropolymerization molecular imprinting technology-based double-parameter composite micro-sensor and preparation thereof
Publication date: 2013
Publication number: CN102901754A

Abstract: Relating to sensors and molecular imprinting technologies, the invention discloses an electropolymerization molecular imprinting technology-based double-parameter composite micro-sensor and a preparation thereof. According to the invention, three electrochemical microelectrode systems are integrated on a same chip, and each electrochemical microelectrode system has its independent micro-electrochemical reaction pool. Through encapsulation by a sealant, the integrated chip can form an open composite measurement pool containing three electrochemical microelectrode systems. In the micro-reaction pool of each electrochemical microelectrode system, by injecting a solution from the outside, a molecular imprinting procedure containing in situ polymerization and ultrasonic elution of template molecules can be implemented separately, thus obtaining a molecularly imprinted sensor. The left and right microelectrode systems of the composite micro-sensor respectively recognize two corresponding molecules due to different molecularly imprinted sensitive membranes, and the electrochemical microelectrode system positioned in the middle is used as a differential detection reference so as to deduct background signals and environmental effects of a test system. The composite micro-sensor provided in the invention can recognize two molecules simultaneously.
