Abstract

The use of conductive polymers for manufacturing microanalytical tools is now a challenging task especially when preparing sensitive biosensing platforms. Using conductive polymers in nanocomposites overcomes several limitations that are caused by the aggregation of organic or inorganic electrocatalysts, because this type of polymer promotes fast diffusion of electroactive species. In addition, the incorporation of conductive polymers improves the analytical response of sensors for multiple applications. For instance, analytical parameters of sensors are closely related to the ability of the polymer to conduct electroactive species and provide a fast charge transfer in electrochemical reactions. This chapter highlights the recent progress made in the preparation methods for conductive polymers and reports their electrodeposition techniques on solid supports. In addition, incorporation strategies for electrocatalysts are discussed for sensing applications of organic and inorganic compounds and cancer biomarkers.
