Conducting polymers in biosensors: A review

Biosensors have gained immense acceptance in the field of medical diagnostics, food safety, environment control and biodefence application due to high sensitivity, specificity, ability for real-time analysis coupled with speed and low cost. Application of conducting polymers (CPs) in biosensors has recently aroused much interest. CPs provide an excellent opportunity for high selective, specific, stable, economic and handy biosensing devices. This paper first introduced different types of CPs, their unique properties and their synthesis, then specific information is provided on their modification for use in biosensors applications
