Fabrication and Application of a Molecularly Imprinted Sensor for Morin Detection
摘要
Abstract
Based on the intermolecular interaction, a molecularly imprinted polymer electrochemical sensor with specific identification of cavity on gold electrode surface was proposed with o-aminophenol as functional monomers and morin as template molecule. The performance and effect of MIP were investigated by cyclic voltammetry ( CV) and differential pulse voltammetry ( DPV) . Factors affecting the properties of sensor, such as polymeric membrane ratio, scanning cycles, elution time and adsorption time were investigated. Substances which had a similar structure to morin was used to compared the selective response. The result showed that the sensor had a good selectivity to morin. Under the optimized experiment conditions, the current response of the imprinted sensor was linear to the concentration of morin in the range of 0 . 05-1 . 7 μmol/L with linear equation as follows: I(μA)= 1. 0800lgc(mol/L)+ 9. 3599(R=0. 9934), and the detection limit of 0. 1 μmol/L. The sensor was used to determine the content of morin in black tea samples, and the recoveries of standard addition were between 104 . 0% and 108 . 0%.关键词
