Special Issue Information
Dear Colleagues,
Optical sensing through molecular or nanostructured probes is a promising strategy for the detection of a wide range of analytes, affording high sensitivity and a fast readout response. Indeed, compared to instrumental technologies (such as HPLC, NMR, GC), this sensing strategy allows a facile and economic use. In particular, emission-based detection is extremely efficient due to the high sensitivity of the fluorescence technique. The development of fluorescent organic probes, properly functionalized with a receptor moiety, leads to optical sensors able to give a measurable or visible response after the interaction with the sub-ppm concentration of the selected analyte. In particular, today these sensors find applications in the medical field, due to the need to detect a vast range of important analytes involved in many diseases.
The target of this Special Issue is to collect the recent advances in this field (research articles and review), in particular concerning the detection of chemical and biological analytes and having a high impact on human life, including but not limited to transition metals, organic and inorganic pollutants, chemical weapons, neurotransmitters, metabolites, and molecules or biomolecules related to important diseases. Topics of interest include but are not limited to the following:
- Fluorescent sensors;
- Optical sensors;
- Intracellular probes;
- Metal ions;
- Metabolites;
- Covalent sensing;
- Supramolecular sensing;
- Smart devices;
- Medical diagnosis.

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.
