Abstract

In the present article, we briefly review the characteristics, synthetic strategies, and notable applications of
conducting polymers and their nanohybrids as transducers in electrochemical biosensors. The conducting
polymers show unusual electrochemical properties, and they can be directly electrodeposited on the electrode
substrate in the form of a thin polymer film which can later be modified with biomolecules. On the other hand, the
nanostructured hybrid materials have beneficial advantages such as high surface area and small dimensions. The
enlarged surface area enhances the interactions between the electrode materials and analytes, which facilitate
adsorption/desorption kinetics for analytes in the materials, which allows a rapid response time and high signal
reproducibility. The conducting polymer-based nanohybrids have several synergistic properties between the
polymer and the nanomaterials, making them promising candidates for application in sensors as transducers.
