摘要：
A highly selective and sensitive electrochemical sensor modified with carboxymethylated, beta-cyclodextrin (CM-beta-CDP) polymer film was fabricated for the determination of dopamine (DA) in the presence of ascorbic acid (AA). The electrochemical behavior of DA and AA at the chemically modified electrode was investigated by cyclic voltammetry (CV) and differential pulse voltammetry. The response mechanism of CM-beta-CDP film for DA was based on the combination of electrostatic and inclusion interaction of CM-beta-CDP for DA, which was distinguished from the response mechanism of the charged po...
