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
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 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 labeled target, it eliminates many of the
disadvantages inherent in 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 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 two and an half years in research
work of surface modification technology, sensors and
electrocatalysis in Prof. Larry Faulkner group ,
University of Illinois at Champaign -Urban. His research interests are mainly in biological/ /chemical
sensor technologies, energy storage systems, organic field effect transistors,
electrochromic device and science in chemistry and materials. He holds 34 issued US
patents and 32 published papers and numerous prestigious awards such as Motorola
Master Inventor Award (Platinum Badge Award). Currently he is
the Distinguished Member of Technical Staff in Motorola and the
member of Motorola Science Advisory Board Association.
He is an active member of the American Chemical Society and Electrochemical Society , and is the
member of NIH Multidisciplinary Study Section and referees for numerous
international ly circulated journals.
