Methylene Blue in Photodynamic Therapy
Photodynamic therapy (PDT) is a treatment modality that utilizes light-sensitive compounds, such as methylene blue, along with light exposure to target and destroy malignant cells. You may find the following components essential to understanding how this therapy functions.
Mechanism of Photodynamic Therapy
PDT operates on a straightforward principle: the interaction of light, a photosensitizer (like methylene blue), and oxygen. When exposed to specific light wavelengths, the photosensitizer becomes excited and generates reactive oxygen species. These ROS lead to cell death, particularly in targeted tumor cells.
Steps in Photodynamic Therapy
-
Administration of the Photosensitizer: Methylene blue is introduced into the body and can be selectively absorbed by abnormal tissues, particularly cancer cells.
