Special Issue Information
Dear Colleagues,
Photodynamic therapy (PDT) is a minimally invasive therapeutic strategy that relies on the activation of photosensitizers (PSs) via light of a suitable wavelength to generate reactive oxygen species (ROS), leading to selective cytotoxic effects. However, many conventional PSs face limitations such as poor water solubility, low photostability, limited selectivity, and suboptimal accumulation in diseased tissues. To address these challenges, nanotechnology has enabled the development of advanced delivery systems that improve the pharmacokinetics, targeting, and photophysical properties of PSs.
This Special Issue aims to showcase recent advances in nanoparticle-assisted PDT, focusing on the design, synthesis, and application of nanosystems that respond to light and complementary physiological stimuli. Nanocarriers such as polymeric nanoparticles, dendrimers, micelles, liposomes, and inorganic nanostructures (e.g., metallic nanoparticles, mesoporous silica, quantum dots, and magnetic nanocarriers) have demonstrated the ability to improve PS stability, enhance ROS generation, control release, and broaden therapeutic applicability.
Applications of interest include oncological therapy and antimicrobial PDT (aPDT) targeting bacterial and fungal infections, with particular emphasis on localized diseases such as periodontitis, peri-implantitis, skin infections, and ocular conditions.
We welcome original research and review articles addressing innovative nanoformulations, novel or enhanced PSs, combination strategies, and preclinical validation studies.

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. Pharmaceutics 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 2900 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.
