  2. Photodynamic therapy - Wikipedia

    en.wikipedia.org/wiki/Photodynamic_therapy

    Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death (phototoxicity). [ 1 ] PDT is used in treating acne , wet age-related macular degeneration , psoriasis , and herpes .

  4. Photosensitizer - Wikipedia

    en.wikipedia.org/wiki/Photosensitizer

    A photosensitizer being used in photodynamic therapy. 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 hydrogen atom from the substrate.

    en.wikipedia.org/wiki/Central_serous_chorio...

    Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.

  6. Antimicrobial photodynamic therapy - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial_Photodynamic...

    The efficacy of antimicrobial photodynamic therapy, using various distinct photosensitizers, has been studied since the 1990s. [ 9 ] [ 7 ] Most studies have yielded positive outcomes, often achieving disinfection levels, as defined by infection control guidelines, exceeding 5 log 10 (99.999%) of microbial inactivation. [ 14 ]

    Dental infections tend to also respond better to photothermal therapy than photodynamic therapy, though both have a strong effect. [ 10 ] [ 11 ] [ 12 ] The efficacy of PDT for antimicrobial usage is limited by the properties of the membrane of the target cell such as the electrical gradient ( membrane potential ) and lipid composition.

    Jablonski diagram of FRET with typical timescales indicated. The black dashed line indicates a virtual photon.. Förster resonance energy transfer (FRET), fluorescence resonance energy transfer, resonance energy transfer (RET) or electronic energy transfer (EET) is a mechanism describing energy transfer between two light-sensitive molecules (chromophores).

    en.wikipedia.org/wiki/Photoimmunotherapy

    Photoimmunotherapy (PIT) is an oncological treatment that combines photodynamic therapy of tumor with immunotherapy treatment. Combining photodynamic therapy with immunotherapy enhances the immunostimulating response and has synergistic effects for metastatic cancer treatment. [1] [2] [3]
