Special Issue Information
Dear Colleagues,
There is currently a rapidly growing demand for the sensitive and selective detection of volatile organic compounds (VOCs) in various domains, including environmental monitoring, air quality control, detection of pollution or gas leaks for personal/public safety, food safety and quality control, non-invasive medical diagnostics, etc. For these applications, portable devices such as miniaturized sensors are preferable for real-time and on-site analyses. Among them, biomimetic olfactory sensors and electronic noses are very promising. In particular, electronic noses, by mimicking human olfaction, consist of an array of sensors with cross-sensitivity to different samples and use advanced mathematical procedures for signal processing based on pattern recognition and/or multivariate statistics. In the last three decades, great efforts have been made for the development of sensitive and robust transduction systems of all types. Nevertheless, due to the limited number of sensors and especially the limited diversity of sensing materials (metal oxides, polymers, etc.), so far, the performance of most existing electronic noses is still far behind what we expect.
Therefore, this Special Issue of Sensors will highlight recent advances in the design and development of novel sensing materials to improve the performance of the olfactory sensors and electronic noses (in terms of sensitivity and selectivity). A particular emphasis will be put on the design of novel biomimetic sensing materials, i.e. the protein engineering of odorant binding proteins (OBPs) and olfactory receptors (ORs), the rational design of peptides by molecular modelling and/or computational screening, biopolymers such as DNA, synthetic receptors, molecular imprinted polymers (MIP), etc. Finally, there is also a particular interest in the applications of these devices in various domains, covering VOC and odour analysis, food and beverage analysis, environmental analysis and biomedical applications.
Submitted papers should present novel contributions and innovative applications. Relevant topical reviews are also welcome.

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.
