Biomedical Engineering Lecture Series Seminar Surface Modified Electrodes and Their Uses in Chemical and Biosensing Friday, January 30, 2009 10:00 AM Xiangqun Zeng, PhD Dr. Zeng received her Ph.D. in Electrochemistry at State University of New York at Buffalo in 1997 under the direction of Professor Stanley Bruckenstein. She continued one year postdoc at Professor Bruckenstein lab after her Ph.D. study. From 1998-2001, she was an assistant professor at the Department of Chemistry at University of Wisconsin Oshkosh. She moved to Oakland University in 2001 and was promoted to be associate professor with tenure in 2005. Dr. Zeng currently directs the chemical and biosensor research group at Oakland University (http://www.oakland.edu/~zeng) that focus on the electroanalysis, surface design and characterization at electrode interfaces. Her current research is cross-disciplinary involving electrochemistry, spectroscopy, material science, bioengineering, biology and medicine, with a focus on electroanalytical and surface chemistry at metal electrode interfaces. She has received various fundings to support her research including Cottrell College Science award in 2000 from Research Corporation, American Chemical Society Petroleum Research fund in 2001, National Institute of Health Grants in 2002 and 2004, and Michigan Academic Commercialization fund in 2005. She received Oakland University Young Investigator Research Excellence Award in 2005. Surface modified electrodes are electrodes with deliberately immobilized materials so that the electrodes display the chemical, biological and other properties of the immobilized molecules. The properties of the surface modified electrodes are closely associated with the physical and chemical properties of immobilized molecules as well as the immobilization processes. This presentation will discuss the molecular design and study of several important materials including conductive polymers, ionic liquids, carbohydrates and recombinant antibodies for fabricating new surface modified electrodes and their applications for studying the fundamental chemical and biological binding processes and for development of improved chemical and biosensors. |
