Sensitive Detection Of Bisphenol Research Articles

Fabrication of a trans-scale bimetallic synergistic enhanced Raman scattering substrate with high surface-enhanced Raman scattering activity

A novel trans-scale bimetallic synergistic enhanced Raman scattering (TBSERS) substrate was fabricated and employed for sensitive detection of bisphenol A (BPA).

Highly specific and sensitive detection of bisphenol A in water samples using an enzyme-linked immunosorbent assay employing a novel synthetic antigen

Bisphenol A is a newly discovered endocrine disrupting chemical found in the environment that has estrogenic properties. With the extensive use of plastic products, the diffusion of bisphenol A from these products has caused serious environmental contamination. The present study investigated the synthesis of bisphenol-A antigen and polyclonal antibodies in order to develop a rapid method for the detection of bisphenol A in water. A carboxyl group was introduced into bisphenol A to create a novel hapten capable of coupling with proteins. A rabbit polyclonal antibody with good specificity was prepared by using the novel synthetic antigen. The obtained antibody had a low cross-reaction with other steroid substances. The half inhibitory concentration of the established method was 1.92 ± 0.06 μg L−1, with the lowest limit of detection being 0.10 μg L−1 and the coefficient of variation being less than 10%. The standard recovery rate of water samples was 95.5–105.0%. The method established in this study is an easy, rapid and specific method used for the quantitative detection of bisphenol A in water samples.

Amplified electrochemiluminescence of lucigenin triggered by electrochemically reduced graphene oxide and its sensitive detection of bisphenol A

An amplified and stable electrochemiluminescent signal of lucigenin on electrochemically reduced graphene oxide-containing sensing platform was obtained, and exhibited obvious analytical properties towards bisphenol A.
