Conducting polymer-based platform for electrochemical sensors

In the last couple of years, most of the work was devoted to synthesize new sensing nanocomposites to improve a sensor performance in terms of sensitivity, selectivity, and biocompatibility. Of those synthesized nanomaterials, conducting polymers composites have been widely used in the construction of sensor surfaces. The synergy of multifunctional materials, recognition elements, and electrochemical methods is improving the selectivity, stability, and reproducibility, thus promoting the development of sensors for assays and bioassays. Polyaniline and gold nanoparticles were used to obtain a nano/micropatterned surface at graphite screen printed electrodes (GSPEs) with applications in the sensors field. The obtained nanocomposite polymeric films were electrochemically characterized.
