Water-Soluble Fluorescent Sensors for Biological Detection

Dear Colleagues,

In the past decades, there has been a growing interest in developing bright and stable fluorescent sensors with a fast response, high sensitivity, and high selectivity. For this purpose, researchers have developed a wide variety of organic and inorganic fluorescent sensing moieties, such as single small molecules, proteins, or nanoparticles. The choice of biological analytes is also very broad, including small molecules such as gases, sugars, and ions, or macromolecules such as DNA, enzymes, and proteins, detected in vivo or in vitro. Most of the time, sensing mechanisms involve energy transfer (e.g., FRET), photoinduced electron transfer, or intramolecular charge transfer between two distinct parts of the (macro)molecules, excited by one or two photons.

This Special Issue aims to emphasize researchers’ creativity in the development of water-soluble fluorescent sensors, ranging from chemistry design to various choices of analytes and different sensing mechanisms.

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.
