Special Issue Information
Dear Colleagues,
One of the innovative directions in the development of analytical biotechnology is the creation of microbial bioelectrochemical systems - modern biotechnological tools that combine high sensitivity and ease of analysis. They can be successfully used to control individual components and integral characteristics in environmental monitoring, the food industry, and clinical diagnostics. Bioelectrochemical systems: microbial biosensors and biofuel cells of various designs and purposes are a promising direction in the development of modern biotechnology. Such systems based on the reactions of living organisms can be effectively used to analyze environmental objects. In particular, they can be used to analyze biochemical oxygen demand, integral toxicity, phenols, surfactants, heavy metals, and other important indicators of industrial pollution. The most important issues in the development of such analyzers are: simplification of the manufacturing technology and maintenance of a biological receptor element, a decrease in the lower limit of the analyzed values, an increase in the long-term stability of receptor systems and an increase in their resistance to toxic wastewater components. The solution of the questions raised is possible both through the development of approaches to obtaining the analytical signal of the biosensor, through the use of various types of highly sensitive transducers, and through the selection of a biological material with high metabolic activity, resistance to toxicants and a wide range of utilizable substrates, and new methods of biomaterial immobilization to increase stability of the analytical system.

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.
