Dear Colleagues,

In the past few decades, fluorescent proteins have been one of the most important tools in the field of life science. This is mainly due to their outstanding luminescence, excellent biological compatibility, and accurate positioning by genetic encoding. Currently, fluorescent proteins are widely applied in cell imaging, labeling interactions between proteins, constructing biological sensors, and so on. Since the discovery of GFP from the jellyfish Aequorea victoria, fluorescent proteins have been improved significantly. By mutating amino acids, nowadays, there are more choices in excitation and emission wavelengths. The photostability and photobleaching also can be controlled according to the specific use scenario. Additionally, to support improvement, the luminescence mechanism of fluorescent proteins has attracted more and more attention. In recent years, some new classes of fluorescent proteins, such as DsRed from the coral Discosoma, have also been discovered, which further expands its potential applications.

This Special Issue encourages authors to submit new research results concerning mechanism analysis, structure designs, and application innovations for fluorescent protein sensors.

The Special Issue topics include but are not limited to:

New sensor design;

Novel applications;

Cell visualization;

Subcelluar localization;

Protein–protein interactions;

The luminous mechanism;

Structure analysis; and

Ultrafast spectroscopy analysis.

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.
