P(DM-co-HEMA)水凝胶电化学传感器的构建及其性能研究
Study on Construction and Properties of P(DM-co-HEMA)Hydrogel Electrochemical Sensors
摘要
Abstract
With dimethyldiallylammonium chloride(DM)as the main component to provide the cationic groups,and with hydroxyethyl methacrylate(HEMA)and N,N-methylenebisacrylamide(MBA)as the auxiliary structural monomers,polyelectrolyte hydrogel film P(DM-co-HEMA)can be successfully prepared.DM provids the hydrogel with good anti-swelling properties,hydrolysis stability and conductivity in an aquatic environment.A dopamine(DA)electrochemical sensor(P(DM-co-HEMA)/GCE)can be constructed by using the hydrogel film modified glassy carbon electrode(GCE).The performance test results show that the prepared P(DM-co-HEMA)/GCE exhibits a good electrochemical response to DA.Within the concentration range of 0.1～0.4 mmol/L and 0.4～2.9 mmol/L of DA,the corresponding values of oxidation peak current and reduction peak current increase linearly with the concentration of DA,with a detection limit of 7.41 µmol/L(signal-to-noise ratio of 3),which indicates that compared with bare GCE,P(DM-co-HEMA)/GCE is characterized with a better stability and anti-interference property.关键词
