As a significant and promising conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT) has attracted considerable attention in the last decade. This review aims at giving a comprehensive illustration about current progress on the synthesis and electrochemical sensing applications of PEDOT-based materials in environmental monitoring, food and drug analysis and health care. PEDOT-based materials, such as PEDOT, functionalized PEDOT and PEDOT composites were fabricated mainly by chemical polymerization and electrochemical polymerization. Various nanostructures with large surface area, high conductivity, fast electron transfer rate, hydrophobic interaction and good biocompatibility were displayed by the PEDOT-based materials. Synergetic effects were enhanced dramatically in electrochemical (bio) sensors by PEDOT composites, especially by those incorporated with versatile nanomaterials. Through this paper, we hope to attract attention from a wider community and inspire researchers to take advantage of PEDOT in approaching scientific challenges and developments.
