Dear Colleagues,

Fluorescent and luminescent biosensors are a highly active and interdisciplinary research field. The field has attracted much attention because of its potential to lead to low-cost, rapid, sensitive, and miniaturized bioanalytical devices. In past decades, we have witnessed a tremendous progress in translations of fluorescent and luminescent biosensors from an academic area of research into a most powerful bioanalytical and diagnostic sensor technology. Especially in recent years, this technology development/transition has been reflected in various research efforts to exploit a variety of miniaturized and, in some cases, multiplex analytical formats, such as microfluidics, microarrays, and paper-based analytical devices for quantitative analysis of a whole spectrum of individual ions, small molecules, peptides, proteins, nucleic oligoes, cells, and cellular vesicles. These progresses make fluorescent and luminescent biosensors indispensable tools in the areas from environmental monitoring, to food/agriculture safety, biological/biomedical assays, and medical prognosis and diagnosis. Many of these applications are characterized by their outstanding sensitivity, capable of detecting concentrations in the nano-/picomolar scales, impressive performance in real-time monitor of biological processes, and multiplex capability in diagnostic assays.

This research topic aims to collect recent developments and applications of fluorescent and luminescent sensors as well as highlight prospective directions in the field. We encourage authors to submit both original research and review articles on, but not limited to, the following topics:

Development of fluorescent and luminescent biosensors (molecules, proteins and nanostructure) based on all aspects of molecular spectroscopic mechanisms:

• Fluorescent/luminescent sensors;
• Bioluminescent/chemiluminescent sensors;
• Forster resonance energy transfer (FRET)-based fluorescent sensors;
• Internal charge transfer (ICT)-based fluorescent sensors;
• Aggregation-induced enhancement (AIE)-based fluorescent sensors;
• Anisotropy-based fluorescent sensors;
• Metal enhanced fluorescent sensors;
• Luminescence lifetime-based sensors;

Applications of fluorescent and luminescent biosensors in biologically-related systems:

• Biological applications;
• Medical diagnostics;
• Immunoassays;
• Point-of-care (POC) diagnostics;
• intracellular sensing;
• wearable chemical sensors;
• microbial sensors;
• Food processes and agriculture;
• Environmental monitoring.

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. Biosensors 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.
