Conductive Polymers-Based Sensors

Because of their ability to sense physicochemical conditions in the surrounding environment and convert the chemical information into detectable electrical and/or visual signals, CPs offer significant promise in various types of sensors such as conductometric sensors, gravimetric sensors, optical sensors, and fluorescence-based sensors. Furthermore, due to a synergistic effect, the combination of CPs with other sensing materials such as carbonaceous materials, metals, metal oxides, metal sulfide, cyclodextrin, elastomer or thermoplastic elastomer polymer matrices, etc., generates diverse composites with enhanced sensing performance. Utilizing the effective energy transfer and the conformational changes of CPs, biosensors are widely applied on the fields including health care, organic immunosensors, enzyme-based biosensors, DNA biosensors, and environmental monitoring. The perspectives of CP-based sensors mainly rely on all solid-state, flexible, stretchable, highly sensitive, and highly selective sensors.
