Special Issue Information

Dear Colleagues,

Fluorescent optosensing materials have received special attention in the development of optical sensor systems due to their reliable and rapid fluorescence response on reaction with analytes. Further exploration of high-performance fluorescence strategies with high fluorescence quantum yield, good stability and long life is still needed. This Special Issue plans to provide an overview of the most recent advances in the field of fluorescent optosensing materials and their applications in the fields of biology, medicine, environment and food. This Special Issue aims to provide selected contributions on advances in the synthesis, characterization, and applications of fluorescent optosensing materials with regard to the identification of and response to analytes.

Potential topics include, but are not limited to:

  • Fluorescent sensing nanoparticles;
  • Structure, characterization and optical properties of fluorescent sensing materials;
  • Mechanisms of fluorescent probes;
  • Application of fluorescent sensing materials in drug delivery;
  • Application of fluorescent probes in the fields of biology, environment and food;
  • Adverse effects of fluorescent probes;
  • Future perspectives for fluorescent probes.

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. Molecules 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 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.

Since Hydrogen Sulfide (H2S) was recognized as a gas transmitter, its detection and quantification have become a hot research topic among chemists and biologists. In this area, fluorescent probes have shown great advantages: fast and strong response, low detection limit and easy manipulation. Here we developed a new fluorescent probe that detected H2S selectively among various bioactive and inorganic salts. This probe was based on the core structure of fluorescein and reacted with H2S through azide-reduction. Great linearity was achieved correlating fluorescence intensity and H2S concentrations in solution. The detection of H2S in cancer cells was also achieved. Full article
