In 1867, the first fluorescent chemosensor was developed by F. Goppelsroder for the detection of Al3+ ion using morin chelate. Later, Prof. Anthony W. Czarnik and Prof. Amilra Prasanna de Silva contributed many seminal works and inspired others in the field of chemosensors. Organic fluorophore moieties have gained tremendous attention as a chemosensor for the detection of various analytes, such as metal ions, anions, and molecules due to their cost-effective synthesis and ability to bind with analytes showing a high association constant and low limit of detection. Various fluorescence mechanisms are involved in the detection of analytes such as chelation-enhanced fluorescence (CHEF), aggregation-induced emission (AIE), photo-induced electron transfer (PET), fluorescence resonance energy transfer (FRET), internal charge-transfer (ICT), and excited-state intramolecular proton-transfer (ESIPT). Furthermore, the concept of fluorescence sensing mechanisms has been extended to molecular logic gates, which interconnect information technology and chemistry. In addition, upon excitation with visible bandgap energy photons, various chemosensors exhibit high fluorescence intensity in the 7.0–9.0 pH range, which makes them suitable for biological applications.
Though several breakthroughs have already been achieved in the field of chemosensing, there is still ample scope for developing new chemosensors which can simultaneously detect, remove, and cure the disease in living cells. We also need to develop chemosensors which can absorb multiple photons having energy in infrared regions and, consequently, make sure cells will not be damaged by low-energy photons during the study.
Authors are encouraged to submit their best experimental as well as theoretical findings that include new chemosensors along with their application in cell imaging studies. We also welcome high-quality reviews for analyte sensing and its practical use in cell imaging studies.

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. Chemosensors 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 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.
