Conducting Polymers as Elements of Miniature Biocompatible Sensor

Abstract

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 bio- compatibility. 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.
