Special Issue Information
Dear Colleagues,
Electrogenerated chemiluminescence, also called electrochemiluminescence (ECL), is the light emission generated from molecular species (luminophores) via the electron transfer process. The main merits of ECL are its excellent selectivity, sensitivity, simplicity, and the possibility of spatial and time control as ECL is triggered by an electrochemical reaction of the luminophores on an electrode surface. Due to these merits of the ECL process, it has become an attractive transduction platform and has received growing interest not only for chemical sensors, but also for biosensors and bioassays. ECL-based biosensors use specific biological recognition elements such as oxidase or dehydrogenase enzymes, antibodies, aptamers, carbohydrate-binding lectins, peptides, and proteins to selectively recognize an analyte and produce an ECL signal change depending upon the analyte concentration. Some of these analytes include the substrates of enzymatic reactions, antigens, carbohydrates, peptides, nucleic acids, and living cells such as E-coli or even cancer cells.
Over the last several decades, numerous studies on ECL chemical sensors and biosensors have been conducted in a variety of fields ranging from chemical analysis, clinical diagnostics, and environmental, water, or food analysis. In addition, a number of new luminophores, mostly transition metal complexes and inorganic semiconductors, have been prepared and immobilized on an electrode surface to be used as a sensitive and biocompatible probe for the detection of analytes. To date, they have successfully verified that ECL-based chemical sensors and biosensors have great potentials to be used in real-world applications. However, the development of highly sensitive and biocompatible luminophores remains a long journey and the practical conversion of ECL chemical and biosensors from basic research to real applications is still a major challenge. This Special Issue of Sensors will cover current research topics in the exciting field of ECL-based chemical and with the aim of discovering how they are fabricated and what merits they have for specific chemical and bioanalytical applications.
We welcome submissions that are related to ECL chemical sensors and biosensors such as developing new ECL luminophores, highly sensitive ECL detection methods potentially used as a transduction platform in chemical and biosensors, a wide range of new applications of ECL-based chemical and biosensors. Both research papers and review articles will be considered. We look forward to and welcome your participation in this Special Issue.

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).
