Patent Title: 6-hydroxynicotinic acid molecularly imprinted polymer piezoelectric sensor and preparation method thereof
Publication date: 2014
Publication number: CN104198322

Abstract: The invention discloses a 6-ydroxynicotinic acid molecularly imprinted polymer piezoelectric sensor and a preparation method thereof. The sensor comprises a piezoelectric quartz crystal gold electrode, wherein a mixture of polyvinyl chloride, tetrahydrofuran and a 6-ydroxynicotinic acid molecularly imprinted polymer are added onto the surface of the piezoelectric quartz crystal gold electrode in a coating manner; after the tetrahydrofuran is volatilized, the 6-ydroxynicotinic acid molecularly imprinted polymer piezoelectric sensor is obtained. The preparation method comprises the following steps: soaking the gold electrode into a NaOH solution and an HCl solution in sequence, further dripping a piranha solution, and finally embedding the imprinted polymer with an inert material PVC (Polyvinyl Chloride). The 6-ydroxynicotinic acid molecularly imprinted polymer piezoelectric sensor is prepared by using a simple and convenient method, the 6-ydroxynicotinic acid molecularly imprinted polymer piezoelectric sensor not only is very high in recognition capability and high sensitivity, but also has the characteristic that the sensor is more precise than a conventional recognition element, can precisely detect the content of 6-ydroxynicotinic acid and has very good development and application prospects in the fields of pesticides and medicines.
