文摘

The electropolymerization of alizarin yellow R on the carbon dots/GCE was carried out for fabrication of electrochemical sensor. The sensor was used for enhanced electrocatalytic oxidation and nanomolar detection of l-cysteine. The sensor was applied for analysis of l-cysteine in real samples with a detection limit of 90  nM at pH 7.
