Special Issue Information

Dear Colleague,

Photodynamic therapy (PDT) is an emerging treatment method for cancer and other diseases. This Special Issue “Photodynamic Therapy in Medicine” is aimed at improving current basic and preclinical knowledge about principles of deep-tissue PDT. This Special Issue will present the synthesis of nanoparticles and up-conversion nanoparticles (UCN) with adsorbed fluorescent dyes that can, upon radiation with near-infrared light, excite clinically approved photosensitizers (PS) via FRET-driven fluorescence and evaluate subsequent photodynamic action and dark cytotoxicity in vitro. UCN constructs are expected to extend the depth in tissue to which PDT can be applied by virtue of their ability to absorb near-infrared light, which can penetrate tissue to a depth of several centimeters. The primary anti-cancer agent generated by the PS is singlet oxygen, which can kill cancer cells. In this project, the stability of UCN and the efficiency of singlet oxygen generation in solution and model cells will be reviewed. The intracellular and extracellular concentrations of singlet oxygen will be valuable to measure by singlet oxygen luminescence for real-time dosimetry in cells. This research is expected to advance the understanding of the use of PDT in medicine.

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. Life 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 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.

Photodynamic Therapy (PDT) is a cancer treatment that uses light, a photosensitizer, and oxygen to destroy tumors. This article is a review of approaches to the treatment of prostate cancer applying upconversion nanoparticles (UCNPs). UCNPs have become a phenomenon that are rapidly gaining recognition in medicine. They have proven to be highly selective and specific and present a powerful tool in the diagnosis and treatment of prostate cancer. Prostate cancer is a huge health problem in Western countries. Its early detection can significantly improve patients’ prognosis, but currently used diagnostic methods leave much to be desired. Recently developed methodologies regarding UCNP research between the years 2021 and 2014 for prostate cancer PDT will also be discussed. Current limitations in PDT include tissue irradiation with visible wavelengths that have a short tissue penetration depth. PDT with the objectives to synthesize UCNPs composed of a lanthanide core with a coating of adsorbed dye that will generate fluorescence after excitation with near-infrared light to illuminate deep tissue is a subject of intense research in prostate cancer.
