The compound provides real time near-infrared (NIR) fluorescence imaging with an extinction coefficient of 2.8 × 10 5 M −1 cm −1 and combinatorial phototherapy with dual photothermal and photodynamic therapeutic mechanisms that may be appropriate for adriamycin-resistant tumors. The particles had a hydrodynamic size of 37.66 ± 0.26 nm ...
Recovery of visual acuity usually follows. Treatment should be considered if resorption does not occur within 3–4 months, [19] spontaneously or as the result of counselling. [1] The available evidence suggests that half-dose (or half-fluence) photodynamic therapy is the treatment of choice for CSR with subretinal fluid for longer than 3–4 ...
Antimicrobial photodynamic therapy (aPDT), also referred to as photodynamic inactivation (PDI), photodisinfection (PD), or photodynamic antimicrobial chemotherapy (PACT), is a photochemical antimicrobial method that has been studied for over a century. [1]
[4] Though photopharmacology is a relatively new field, the concept of using light in therapeutic applications came into practice a few decades ago. Photodynamic therapy (PDT) is a well-established clinically practiced protocol in which photosensitizers are used to produce singlet oxygen for destroying diseased or damaged cells or tissues. [2]
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.
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
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.
