Fotodynamická

Fotodynamická is a term that relates to photodynamic processes. It is often used in the context of photodynamic therapy (PDT), a medical treatment that uses a combination of a photosensitizing drug and light to kill diseased cells. The photosensitizing drug is administered to the patient and selectively accumulates in the target cells. When exposed to light of a specific wavelength, the drug is activated and produces a form of oxygen that damages and destroys the diseased cells. PDT is used to treat various conditions, including certain types of cancer, skin conditions like actinic keratosis and acne, and macular degeneration. The effectiveness of PDT depends on several factors, including the type of photosensitizer used, the wavelength and intensity of the light, and the duration of the treatment. Research continues to explore new applications and improvements in photodynamic therapies. The term can also be applied more broadly to any process involving light and chemical reactions, particularly in biological systems.
