Abstract: Electrochemical analysis is a promising method for biosensing. In our current work, a highly sensitive nanostructured electro- chemical biosensor based on a 3D sensing element featuring uniformly deposited gold nanoparticles has been developed. The barrier-layer surface of an anodic aluminum oxide (AAO) membrane was adopted as the substrate. A gold thin-film was sputtered onto the substrate, followed by a uniform electrochemical deposition of gold nanoparticles (GNPs) on the gold thin-film. The detections of the dust mite antigen Der p2, allergy patient’s serum, allergy disease related gene mutations (SNP and Haplotype), dengue virus-receptor binding, hepatitis B virus DNA, Alzheimer’s (AD) Aβ protein have been successfully carried out using electrochemical impedance spectroscopy (EIS) analysis.
Bio: Dr. Gou-Jen Wang received the B.S. degree in 1981 from National Taiwan University and the M.S. and Ph.D. degrees in 1986 and 1991 from the University of California, Los Angeles, all in Mechanical Engineering. Following graduation, he joined the Dowty Aerospace Los Angeles as a system engineer from 1991 to 1992. Dr. Wang joined the Mechanical Engineering Department at the National Chung-Hsing University, Taiwan in 1992 as an Associate Professor and became a Professor in 1999. From 2003 to 2006, he served as the Division Director of Curriculum of the Center of Nanoscience and Nanotechnology. From 2007 to 2011, he was the Chairman of the Graduate Institute of Biomedical Engineering, National Chung-Hsing University, Taiwan. From 2014, he has been the Vice Director of the Biotechnology Center, National Chung-Hsing University, Taiwan. Dr. Wang will serve as Dean of the Engineering College, National Chung-Hsing University, Taiwan starting from August, 2015. In 2008, he served as the Conference Chair of the Microfabrication, Integration and Packaging Conference (April/2008, Nice, France). From 2009, he is a Committee member of the Micro- and Nanosystem Division of the American Society of Mechanical Engineers. His research interests include Biosensors, Biomedical micro/nano devices, Nano fabrication, Tissue Engineering and Regenerative Medicine.
