Dr Liming Dai joined the University of Dayton in 2004 as theWright Brothers Institute Endowed Chair Professor of Nanomaterials. He received his Ph.D. in chemistry from the Australian National University in 1990 under the supervision of Professor John W. White. He accepted a postdoctoral fellowship in physics from the Cavendish Laboratory at the University of Cambridge, and a visiting fellowship from the Department of Materials Science and Engineering at the University of Illinois. Thereafter, Dai spent 10 years with CSIRO in Australia. Dr Dai’s expertise lies across several fields, including the synthesis, chemical modification, and device fabrication of conjugated polymers, fullerene-containing polymers, and carbon nanotubes, with nearly 200 publications and several mongraphs. He has received several awards including the 2006 Sigma Xi’s George Noland Research Award, and the 2006 Outstanding Engineers and Scientists Award from the Affiliate Societies Council of Dayton.

Abstract

Conjugated conducting polymers and carbon nanotubes, both of which possess a conjugated structure of alternating carbon–carbon single and double bonds for the delocalization of π-electrons, are two important classes of electrochemical sensing materials. The combination of carbon nanotubes with conducting polymers or other functional materials (e.g., DNA chains, proteins, metal nanoparticles, carbon fibres) was found to create synergetic effects, that provide the basis for the development of numerous novel sensors with a high sensitivity, good selectivity, excellent environmental stability, and low power consumption. This article reviews recent developments in this exciting new area of electrochemical sensing by presenting the rational strategy of the author’s group in the design and characterization of these new electrochemical sensors based on architectural diversity of the π-conjugated structure.
