Photodynamic Effect on Cellular Components (PDT Effect)
- Target
- PDT Effect
- Molecular classification
- Biological process, Oxidative stress pathway
01
Overview
The photodynamic effect refers to the cellular and molecular consequences of photodynamic therapy (PDT). It involves the use of a photosensitizer, light, and oxygen to generate reactive oxygen species (ROS) that cause oxidative damage to cellular components, leading to cell death. The selectivity of PDT arises from preferential accumulation of photosensitizers in diseased tissues and spatial control of light delivery.

02
Mechanism of action
Photosensitizer absorbs light and generates reactive oxygen species (ROS), leading to oxidative damage of cellular components (lipids, proteins, nucleic acids) and subsequent cell death.
