Photosensitizer - Wikipedia
网页Photosensitizers are light absorbers that alter the course of a photochemical reaction. They usually are catalysts. [1] They can function by many mechanisms, sometimes they donate an electron to the substrate, sometimes they abstract a …
Recent Strategies to Develop Innovative Photosensitizers for …
网页2021年9月28日 · This review presents a robust strategy to design photosensitizers (PSs) for various species. Photodynamic therapy (PDT) is a photochemical-based treatment approach that involves the use of light combined with a light-activated chemical, referred to as a PS. Attractively, PDT is one of the alternatives to conventional cancer treatment due to …
A bright future for photosensitizers | Nature Chemistry
网页2020年3月16日 · Photoluminescent complexes traditionally feature precious metals and they work through generating long-lived excited states that suppress non-radiative relaxation processes. This is often achieved...
Photosensitizers for Photodynamic Therapy - PubMed
网页As an emerging clinical modality for cancer treatment, photodynamic therapy (PDT) takes advantage of the cytotoxic activity of reactive oxygen species (ROS) that are generated by light irradiating photosensitizers (PSs) in the presence of oxygen (O 2 ).
Photodynamic Therapy Review: Principles, Photosensitizers, …
网页2021年8月25日 · Compared to conventional therapeutic modalities, PDT presents greater selectivity against tumor cells, due to the use of photosensitizers that are preferably localized in tumor lesions, and the precise light irradiation of these lesions. This paper presents a review of the principles, mechanisms, photosensitizers, and …
Photosensitizer - an overview | ScienceDirect Topics
网页Photosensitizers are molecules that can be activated by light in order to generate ROS that can damage cell structures from microorganisms or from diseased mammalian cells leading to cell death. Ideally, photosensitizers should be relatively easy to synthesize as a single pure compound, have low levels of cytotoxicity in the dark, and have no ...
