Interdigitated electrodes (IDEs) that have a series of parallel microband electrodes with alternating microbands connected together were utilized in electrochemical impedance spectroscopy (EIS) to build a label-free human immunoglobulin A (IgA) immunosensor. Anti-human IgA (anti-IgA) was employed as an IgA receptor and was covalently immobilized on the IDE(More)
Glucose oxidase (GOx) was immobilized in the organic-inorganic Langmuir-Bldogett (LB) films consisting of octadecyltrimethylammonium (ODTA) and nanosized Prussian blue (PB) clusters. The amperometric glucose biosensors based on the LB films were fabricated and tested. It was found that the sensors exhibited a clear response current under an applied voltage(More)
A novel glucose biosensor with an immobilized mediator was studied using electrochemical impedance spectroscopy (EIS) and amperometry measurements. The biosensor has a characteristic ultrathin form and is composed of a self-assembled monolayer anchoring glucose oxidase (GOx) covered with Langmuir-Blodgett (LB) films of Prussian blue (PB). The immobilized PB(More)
