Dear Colleagues,

This special issue highlights the use of fluorescence for detecting low molecular weight chemicals. Fluorescence is highly effective for discriminating the presence of a target over the spectrally complex background inherent in real-world samples. Fluorescence lifetime measurements, fluorescence polarization, and fluorescence energy transfer provide mechanisms for measuring chemicals in solution. Fluorescence of dye-laden particles, quantum dots, and luminescent proteins provide methods for measuring intracellar chemical changes. On a sensing surface, a fluorescent signal also provides greater sensitivity than measurement of mass change as a target binds to a sensor surface due to significant background signal from nonspecific adsorption of other sample components. Polymers that fluoresce upon target recognition are opening opportunities for sensing in air as well as liquids. Two photon excitation, fluorescence energy transfer, fluorescence quenching and chemically modulated fluorescence are being used to generate novel sensing strategies. New fluors, light sources and detectors are continually expanding the opportunities for fluorescence measurements with inexpensive and even point-of-use systems. This special issue of sensors will focus on the use and application of fluorescent chemosensors in medical, biological, environmental, and analytical fields.

Submission

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 monthly 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 1600 CHF (Swiss Francs).
