A twisted micro-channel capillary electrophoresis amperometric detector was fabricated in this study. It was used for detection of a group of phenolic compounds, considered endocrine disruptors or structurally similar to it. The microchip could detect as low as 1 μM of test analyte, such as bisphenol A (BPA) and butylphenol after their effective separation in microchannel. This approach was further applied in detection of these contaminants in Styrofoam food container used in many East Asian countries for packaging of instant noodle, a popular fast food.
