Abstract
The photodynamic therapy (PDT) is a noninvasive and selective treatment for cancer and otherdiseases. The excitation of a photosensitizer by a laser with a specific wavelength. This excitedphotosensitizer can react with oxygen present in biological systems, generating reactive oxygenspecies (ROS) and triggering cellular damage. To do so, the photosensitizer must undergo anIntersystem Cros…
