Special Issue Information
Dear Colleagues,
Bio-impedance spectroscopy (or dielectric spectroscopy) is the measurement of the complex impedance of a biological sample over a range of frequencies using time-varying electric, magnetic or electromagnetic excitations. The purpose is to use the specifics of the measured spectra to obtain information on the physical, chemical, or cellular properties of the sample. The shape of the spectra is typically composed of multiple dispersion regions that mark the dominance of different energy transmission mechanisms depending on frequency; from ionic diffusions at low frequencies to cellular capacitances or polarization at radio frequencies, to molecular relaxations in the microwave range.
It has long been shown that characteristics of these dispersions correlate to properties such ripeness and injury, across a range of fruits, vegetables, meats, and other foodstuffs. However, the picture is far from complete. There are still many unknowns on how cellular change, decay, damage, or other physiological processes impact the dispersions, and the reverse, how to use the shape of the spectra to make inferences about these properties. Moreover, there is still much research required to derive from this fundamental science, new instrumentation and tools for agri-food systems; potentially improving quality yields and reducing losses in production processes from farm to fork.
This Special Issue “Applications of Bio-Impedance Spectroscopy in Agrifood Systems and Food Analysis” welcomes contributions of original research or comprehensive review submissions about reporting the latest research progress and development in the analytical field of Bio-impedance Spectroscopy.

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. Chemosensors 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 2700 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.
