Abstract: Poly(3,4-ethylenedioxythiophene) or PEDOT has been demonstrated in various biomedical
applications, ranging from biosensing to medical bionics. Being a conductive biointerface, PEDOTs can beserved as an electrode for either electrochemical biosensing or to provide electrical stimuli on attachedbiomolecules. The functional groups on PEDOTs play an important role for the modification of surface
property. In this presentation, I would like to introduce our strategies to manipulate the surface properties ofPEDOT thin films for sensing applications. The control of functional density is a key for tuning thebio-recognition event. Besides, the surface properties, such as morphology and charges, are also critical tothe detection sensitivity. For example, the control of surface charge can enhance the interaction between
charged biomolecules, such as dopamine, and PEDOT surfaces through coulomb force, which leads to ahigher detection of these biomolecules. The recognition between specific molecules and functional groups,
including phosphorylcholine and boronic acid groups, can also be used for the detection purpose. The
recognition process between these functional groups on PEDOT thin films and targeted biomolecules aregenerally monitered by using a quartz crystal microbalance. The attached biomolecules usually alter thecharge distribution on PEDOT surfaces, which can also be measured by using an electrochemical technique.
Furthermore, the influence of non-specific binding and anti-fouling properties on the sensing will beemphasized in this presentation.
Brief Resume: Prof. Lou received his B.S. (in Chemistry) and M.S. (in Materials Science and Engineering)from National Taiwan University in 1996 and 1998, respectively. He then went to United States in 2001 andreceived his Ph.D. degree (in Materials Science and Engineering) from the University of Florida in 2005. Prior
to joining the Department of Materials Science and Engineering at the National Taiwan University in 2015, hewas a post-doctoral research fellow at Institute of bioengineering and Nanotechnology, Singapore from 2006
to 2009, an ASI research scientist at RIKEN Advanced Science Institute, Japan from 2009 to 2013 and anassistant professor at Department of Materials Science and Engineering, National Cheng Kung University,Taiwan from 2013 to 2015. His current research interests include organic conducting materials, biointerfaces,
electrochemical biosensors, bioelectronics, and stimuli -responsive materials for bioengineering applications.
He has published more than 30 papers in the field of conducting polymers. Because of his achievement in thefield, in 2013, he was invited to be as a guest editor of a top journal in polymer science, Polymer Reviews, toorganize a special issue “conducting polymers as biomaterials and biointerfaces”.
