Dear Colleagues,

The main topic of this Special Issue is the development of (bio)sensors and their applications for food safety and quality, as well as in environmental monitoring. In this regard, this Special Issue aims to collect original articles that present research advances in the design, fabrication, and application of high-performance (bio)sensors implementing new principles, strategies, methods, and technologies. Additionally, reviews reflecting current hotspots, new challenges, and future perspectives of (bio)sensors in the two important application areas are particularly welcome.

Safe food and benign environment are the two basic factors of human living and societal development. (Bio)sensors are considered efficient tools to ensure food safety and quality, as well as protect the environment. In this regard, interesting principles, strategies, and methods are being proposed to design, develop, and fabricate (bio)sensors. Moreover, the introduction of nanomaterials endows (bio)sensors with a promising future in food and environmental analyses. Biosensors based on various sensing modes (naked eye, colorimetric, smartphone-based, fluorescent, electrochemical, photoelectric, SERS, chemiluminescent, mass-based, thermal, etc.) and using various recognition elements (natural enzymes, artificial enzymes, DNA/aptamers, antibodies/antigens, molecularly imprinted polymers, etc.) are satisfying the growing needs of methods and devices for the rapid, reliable, and high-performance detection of targets (toxic ions; pesticides, veterinary drugs, and related biomarkers; pathogenic bacteria; antibiotics; toxins; organic pollutants; food additives; etc.) in food and environmental matrices.

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. Molecules 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 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.
