要旨

A novel electrochemical sensor was fabricated for the determination of bisphenol A (BPA) based on a signal amplification strategy with polyacrylamide and multiwalled carbon nanotubes (PAM–MWCNTs). The modified electrode significantly enhanced the oxidation peak current and lowered the oxidation overpotential to improve the sensitivity. Several important parameters which can influence the performance of the sensor were studied and optimized. The sensor showed a fast and sensitive response for the quantitative determination of BPA under optimum conditions. It exhibited a good linear relationship range from 5.0 nmol L−1 to 20 μmol L−1 and the detection limit was 1.7 nmol L−1, (S/N = 3). The sensor exhibited remarkable sensitivity (3.830 μA (μmol L−1)−1). Furthermore, the fabricated sensor showed an excellent result for the detection of BPA in milk samples.

Analytical Methods welcomes early applications of new analytical and bioanalytical methods and technology demonstrating the potential for societal impact. We require that methods and technology reported in the journal are sufficiently innovative, robust, accurate, and compared to other available methods for the intended application. Developments with interdisciplinary approaches are particularly welcome. Systems should be proven with suitably complex and analytically challenging samples. We encourage developments within, but not limited to, the following technologies and applications: global health, point-of-care and molecular diagnostics biosensors and bioengineering drug development and pharmaceutical analysis applied microfluidics and nanotechnology omics studies, such as proteomics, metabolomics or glycomics environmental, agricultural and food science neuroscience biochemical and clinical analysis forensic analysis industrial process and method development
