PACIFIC RIM MEETING ON ELECTROCHEMICAL AND SOLID-STATE SCIENCE
Abstract
A capillary electrophoresis amperometric detector was fabricated using Prussian blue (PB) modified indium tin oxide (ITO) electrode and twisted micro-channel 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 could detect as low as 1 µM of test analyte. 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.
