Title: Aptamer based electrochemiluminescent determination of bisphenol A by using carboxylated graphitic carbon nitride. Author: Cao HX, Wang L, Pan CG, He YS, Liang GX. Journal: Mikrochim Acta; 2018 Sep 17; 185(10):463. PubMed ID: 30225568. Abstract: An electrochemiluminescence (ECL) based assay is described for the determination of the endocrine disruptor bisphenol A (BPA). The method is based on the use of carboxylated graphitic carbon nitride (C-g-C3N4) carrying an immobilized aptamer against BPA. In the presence of BPA, the ECL signal decreases due to ECL energy transfer from excited-state C-g-C3N4 to the BPA oxidation product. Under the optimal conditions, ECL intensity increases linearly in the 0.1 pM to 1 nM BPA concentration range. The detection limit is as low as 30 fM. The assay has excellent sensitivity, outstanding stability and high selectivity. It was applied to the determination of BPA in spiked water samples.
