Many biological assays, such as diagnosis of genetic diseases, analysis of sequence polymorphisms, and study of receptor-ligand interactions, are based on sophisticated analytical tools to detect events related to the interaction between probe and target molecules.  While these molecular detection technologies have traditionally relied on radioactive isotopes or fluorescent labels to monitor probe-target interactions, methods for the electrical detection of molecular interactions provide an attractive alternative.

Labelless electrochemical detection techniques, based on the detection of alterations in the electrical properties of an electrode arising from interactions between probe molecules on the surface of the electrode and target molecules in the reaction mixture, have been developed. Electrochemical doping and “undoping” processes of conjugative conductive polymers are used to amplify the detection signal. Unique A unique covalent binding method significantly increases the detection sensitivity and specificity. Fast impedance measurement in the high frequency range is designed to reduce total assay time.  Based on these findings, bioarray chips were fabricated. DNA and different proteins were detected with superior sensitivity and specificity in comparison to existing technologies.  Since this method does not require a labeled target, it eliminates many of the disadvantages inherent in the use of radioactive, fluorescent or redox (electrochemical labeling detection method) labels to discern molecular interactions. The sensor system can be portable and wireless devices, which are safe, inexpensive, and highly sensitive. In particular, it is convenient for immunoassays since as patient samples cannot be labeled and some proteins cannot be detected by a sandwich assay.

Dr. Changming Li earned a BA in Polymer Chemistry from Chinese University of Science and Technology and a Ph.D. in Physical Chemistry From Wuhan University,, China, specializing in electrochemistry, biological and /chemical sensor technology, and material science.  He spent conducted two and an half years in research work ofon surface modification technology, sensors, and electrocatalysis in Prof. Larry Faulkner’s group, at University of Illinois at, Urbana-Champaign-Urban. His research interests are mainly in  bioin biological//chemical sensor technologies, energy storage systems, organic field effect transistors, electrochromic devices, and science in chemistry and materials. He holds 34 issued US patents and 32 published papers, and numerous prestigious awards such as the Motorola Master Inventor Award (Platinum Badge Award). Currently he is the Distinguished Member of Technical Staff in Motorola and the member of a Motorola Science Advisory Board AssociationAssociate. He is an active member of the American Chemical Society and, of the Electrochemical Society,, and is the member of the NIH Multidisciplinary Study Section, and referees for numerous internationally circulated journals.
