Electrochemical Sensing Technologies for Oxygen Monitoring

Dear Colleagues,

Electrochemical sensors are devices that provide information about the composition of a system in real-time by coupling a chemically selective layer (the recognition element) to an electrochemical transducer (the electrode). The use of electrons for signal acquisition (considered a clean model for analytical applications, with no waste generation), miniaturization in portable devices, fast analysis, and low production cost allow for the popularization of these methods (e.g., as commercial glucose sensors or respiratory carbon dioxide sensors). In addition, the development of electrochemical sensors aids in the improvement of other techniques, such as chromatography and electrophoresis detectors. Regardless of the application (the automotive industry, medicine, industrial safety, modified atmospheric packaging, and many more), the majority of oxygen sensors are designed to measure the quantity of oxygen in the air or in an indoor closed environment. They typically measure between 0.01% and 25% oxygen and can also be used for monitoring oxygen depletion. Electrochemical oxygen sensors are primarily used to measure oxygen levels in ambient air; some of them produce their own analog current, making them useful for measuring oxygen gas in battery-operated underwater diving and hand-held personal safety devices. This Special Issue highlights recent advances in the field of electrochemical oxygen sensors. It reviews the principles and architectures of micro-nanofabricated sensors, including electrogalvanic sensors, zirconia, Clark electrodes, and related sensor systems. It is open to researchers, manufacturers, and specialists in medical, industrial, and scientific fields. Topics of interest include, but are not limited to, new selective molecular recognition surfaces and materials, the physics and chemistry of oxygen sensors and sensor materials, synthesis/fabrication, the characterization of novel compositions, emerging technologies, and applications including nanosensors, sensor-leveraging nanotechnology, etc.

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. Oxygen is an international peer-reviewed open access quarterly 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 1000 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.
