Special Issue Information
Dear Colleagues,
Photodynamic therapy (PDT) is an effective and valuable clinical procedure for the treatment of cancer or microorganisms. This clinical method combines a photosensitizer (PS), molecular oxygen, and visible or near-infrared light irradiation for the production of cytotoxic reactive oxygen species (ROS), leading to the destruction of cancer cells or microorganisms. Comparing this method with conventional therapies, PDT has several returns because it is a relatively non-invasive procedure. Because irradiation is restricted to the biological target, and the PS accumulates mainly in a specific site, it provides a lower systemic toxicity and a selective destruction. The PDT methodology also has a great tolerability profile, the absence of particular resistance mechanisms, a great cosmetic outcome, and the capability to promote the immune approach. Nevertheless, the PDT has certain limitations, and therefore, there is a substantial possibility for development, particularly in the area of new efficient PS drugs. Promising PS should be logically designed to match the features of an ideal PS drug.
The purpose of this Special Issue centered on Photodynamic Therapy (PDT) is to present the latest information in this topic, especially new PS drugs, their photochemical and photobiological properties, and cancer/microorganism therapies. Special importance is dedicated to the design and synthesis of the PS and to their photophysical properties. Moreover, the biological evaluation of each formulation will be emphasized, expecting that the collected knowledge will encourage the development of other effective photoactive drugs. We invite original research manuscripts and comprehensive reviews covering recent findings related to the abovementioned topics.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
