Special Issue Information

Dear Colleagues,

Recent advances in key fields, such as artificial intelligence, digital electronic sensors design, material sciences, microcircuit design, software innovations and electronic systems integration, have contributed to the development of electronic sensor technologies applicable to several research fields, including food, environmental, pharmaceutical and biomedical areas. Electronic tongues (E-tongues) are electrochemical devices (e.g., potentiometric, voltammetric, amperometric, etc.) comprising multi-sensor arrays that, at first glance, aim to mimic basic taste sensations (e.g., acid, bitter, umami, salty and sweet). Usually, these sensors are non-specific, cross-sensitivity and poorly selective, generating large amounts of data per analysis, and, as such, require the use of chemometric tools to extract the best information for establishing predictive multivariate statistical models that relate the sensors signals to their physical meaning. Recently, the use of more specific E-tongue devices has also attracted researchers’ attention, leading to the appearance of bioE-tongue systems, based on the use of enzymes or RNA/DNA aptamers. Thus, scientific and industrial interest, as well as the application fields of E-tongues, have grown enormously. This Special Issue is devoted to the most recent developments in the area of E-tongue technology, including E-tongue design, chemical sensors and biosensors applied, innovative signal acquisition and data processing, practical implementation, in particular for food analysis, biomedical applications and environmental evaluation.

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 papers will be 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. Biosensors is an international peer-reviewed open access monthly 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 1800 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.
