Special Issue Information
Dear Colleagues,
The development of advanced sensing approaches for food control and environmental monitoring is a challenging and increasingly important research domain. In recent years, significant progress has been made toward the development of chemosensors and nanosensors for both food and environmental analysis involving a range of transduction approaches. Colorimetric detection is particularly convenient and valuable due to its simplicity, cost-effectiveness and potential portability. The development of miniaturized detectors and, especially, the impressive emergence of ubiquitous everyday IT and communication devices, such as smartphones and tablets, as platforms for non-conventional optical sensing has prompted the development of colorimetric assays that provide reliable analytical information.
This Special Issue highlights advancements in colorimetric sensing for food and environmental analysis. The topics covered in the Special Issue include but are not limited to the synthesis, design, and application of molecular chromogens and plasmonic nanoparticles for food safety control and/or environmental monitoring. Special attention will be paid to multiplexed sensors, colorimetric sensor arrays, and colorimetric sensing films for smart packaging. Contributions involving smartphone cameras and smartphone-based spectrometers combined with colorimetric assays performed in paper-based analytical devices and lab-on-a-chip systems are particularly appreciated. Original research articles and reviews that significantly contribute to the field are welcome in this Special Issue.

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.
