Monitoring of endocrine disruptors by capillary electrophoresis amperometric detector

A capillary electrophoresis amperometric detector was fabricated using Prussian blue (PB) modified indium tin oxide (ITO) electrode and twisted microchannel configuration. These devices were used for detection of endocrine disruptors, such as bisphenol A (BPA) and butylphenol after their effective separation in microchannel. The microchip had a limit of detection (LOD) as low as 59 nM for analytes. This approach was further applied in detection of these contaminants in Styrofoam food container used in many East Asian countries, such as Korea and China, for packaging of instant noodle, a popular fast food.
