The use of organic conducting polymers (CPs) in the development of electrochemical sensors and biosensors has been expanded tremendously in the last decade for the monitoring of key analytes in bio-medical, environmental, and food safety applications. CPs-based electrochemical sensors and biosensors have emerged as powerful analytical devices that can provide fast, reliable, sensitive, and versatile analytical measurements, including in vivo applications. Several CPs, such as polypyrrole (PPy), polyaniline (PANI), poly(3,4-ethylenedioxythiophene) (PEDOT), and their derivatives, have been intensively investigated in the electrode surfaces modification for sensing applications. The modulation of the electrochemical and electrocatalytic properties of CPs layers by incorporation of metal nanoparticles, redox mediators, carbon materials, and biomolecules ensures the improvement of the sensitivity and selectivity of the sensors.
This Special Issue aims to provide an overview of the recent progress and developments in the area of electrochemical (bio)sensors based on electrodes modified with CPs and (bio)composite materials including novel preparation and electropolymerization procedures, advanced sensing materials, innovative surface functionalization and detection strategies, and selected applications in the chemical sensing of various species like neurotransmitters, antioxidants, and organic and inorganic pollutants. Reviews and original research papers dealing with CPs-based electrochemical sensors fabrication, characterization, and applications in sensing of key analytes in bio-medical, agri-food, and environmental samples are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
