关键字:PAMAM; CdSe QD; beta-cyclodextrin; Electrochemiluminescence (ECL); o-aminophenol
摘要:A stable and sensitive electrochemiluminescence (ECL) detection protocol of o-aminophenol was developed, which was based on CdSe quantum dots (QDs) and the cavity structure of beta-cyclodextrin. In this experiment, the working electrode was prepared by PAMAM and CdSe QD and beta-cyclodextrin using layer self-assembly method under the infrared lamp. Under the optimum conditions, a good linear relationship with the concentration of o-aminophenol from 1.0 x 10(-7) mol.L-1 to 8.0 x 10(-6) mol.L-1 and the detection limits as low as 2.3 x 10(-8) mol.L-1 (3 sigma) were achieved. Good selectivity and repeatability are advantages of the sensor which is feasible.
