Special Issue Information
Dear Colleagues,
There is a large demand for volatile chemical sensors that leverage biological principles and attain higher sensitivity and selectivity for complex odor sensing in natural environments. Biological olfaction has optimized the odor coding principles over millions of years of evolution and several biological principles, including, cross-selective chemosensory array, combinatorial encoding schemes, and sparse decoding approaches, are routinely implemented in portable electronic-nose sensors, which are engineered odor sensors that employ biological principles of one-shot odor recognition.
In this Special Issue, advances of odor biosensors that implement various aspects of biological olfaction will be covered. This will include odor biosensors that (a) employ biological computational rules in engineered odor sensors, (b) incorporate biological sensory components in engineering platforms as hybrid sensing devices, (c) directly harness biological olfactory sensory systems to perform odor sensing, and (d) demonstrate the applications and limits of biological odor sensors (e.g., canine and insects) in disease diagnosis and homeland security applications.

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.
