Conducting Polymers in Biosensing: a review

Medical diagnostics and, to a lesser extent, pharmacy are two of the most prominent applications of organic conducting polymers (CPs). Polymers that conduct electricity, such as polyaniline (PANI), polypyrrole (PPY), polythiophene (PTh), and poly (3, 4-ethylenedioxythiophene), PEDOT, are frequently employed in sensor and biosensor design. Some unique CPs are used in the design of electrochemical biosensors, such as polypyrrole-based functional layers. Biosensors based on conducting polymer composites with other materials are also under investigation. The purpose of this communication is to discuss the manufacturing and applications of these CPs in medical diagnosis and associated applications.
