Conducting polymers (CPs) as well as conducting polymer nanoparticles seem to be very applicable for the development of various analyte-recognizing elements of sensors and biosensors. This chapter reviews mainly fabrication methods as well as application of conducting polymers in sensors. Conducting polymers (CPs) have been applied in the design of catalytic and affinity biosensors as immobilization matrixes, signal transduction systems, and even analyte-recognizing components. Various types of conducting and electrochemically generated polymer-based electrochemical sensors were developed including amperometric catalytic and potentiodynamic affinity sensors. A very specific interaction of analyte with immobilized biological element results in the formation of reaction products.

Conducting polymers (CPs), the so-called “fourth generation of polymeric materials”, can solve essential problems in biosensing technologies due to their unique material properties and implementation in innovative device systems. CPs have excellent biocompatibility. They can provide advantageous interfaces for bioelectrodes owing to their hybrid conducting mechanics, combining both electron and ionic charge carriers. Many (i.e. glucose) biosensors use immobilized enzymes to form a selective layer on CP structure. Miniaturization of sensors is a new requirement. Mini sensors are portable and wearable with low utilization of sample and cost-effective technology of production.
