PHOTODYNAMIC Meaning and
Definition
-
Photodynamic refers to a process or treatment involving the use of light and a photosensitizing agent to induce a reaction or response in a biological system. It specifically pertains to a technique that combines light and a chemical substance to activate a therapeutic or diagnostic effect in living organisms.
In the field of medicine, photodynamic therapy (PDT) is a procedure that employs a photosensitizer, which is a light-sensitive drug, to target and destroy abnormal or cancerous cells. The photosensitizer is administered to the patient either orally or intravenously and is selectively absorbed by the target cells. The light source is then applied to the specific area where the photosensitizer has accumulated, leading to the activation of the drug and subsequent cell destruction. Photodynamic therapy has shown promise in treating various conditions, including types of cancer, skin disorders, and infections.
These techniques also find applications in the field of photodynamic diagnosis (PDD), where the photosensitizer is used to detect and locate abnormal or cancerous cells. By activating the photosensitizer with light, certain tissues or cells can be visually distinguished from the surrounding healthy tissue, aiding in the diagnosis and staging of diseases.
Overall, photodynamic refers to the interaction between light and a photosensitizing agent to achieve therapeutic or diagnostic effects in living systems, making it an essential tool in various medical and scientific applications.

Etymology of PHOTODYNAMIC
The word "photodynamic" is derived from two root words: "photo-" and "dynamic".
The prefix "photo-" originates from the Greek word "phōs", meaning "light". It is commonly used in scientific terminology related to light, such as "photoelectric", "photography", or "photosynthesis".
The term "dynamic" comes from the Greek word "dunamis", which translates to "power" or "force". It refers to something that is characterized by energy, motion, or change.
In the case of "photodynamic", the combination of "photo-" and "dynamic" expresses the idea of an interaction or process that involves light and power, typically referring to a photodynamic therapy or photodynamic action.
