ABSTRACT
The conducting polymers (CPs) are treated as new encouraging materials used as electrodes for implanted bioelectronics and biosensors due to the similarity of their mechanical properties with the biological tissues. The major challenge in the process of implantation is preventing the undesirable protein adhesion and binding of the cell tissues within biological fluids. The adsorptions of the fluids are responsible for the failure of the implanted devices, which is a significant challenge for the long-term use of CPs. Hence, to solve these problems, amazing polymers having antifouling properties are developed. The antifouling coatings are developed with paints comprising polyaniline and show the performance of antifouling on the substrates of PVC and metals. The electrochemical biosensing materials having antifouling properties were designed based on the CP poly(3,4-ethylenedioxythiophene) (PEDOT) implanted with designed peptides. The peptides developed and designed contain the sequences of antifouling, which were attached to the surface of an electrode with the electrochemical polymerization of PEDOT. Hence, the antifouling peptides planting designed in CPs provide an amazing pathway for the development of electrochemical sensors use for biomarkers assaying in biological samples. The epoxy-based paint is now synthesized, which normally consists of epoxy resin and polyaniline with nanorods of ZnO as additive material, which exhibits excellent antifouling properties, if applied on carbon steel. In this chapter, the synthesis, strategies, challenges, and potential applications of paints, coating materials, biosensing, electrode materials, and modem medical applications are specifically focused on.
