In the context of cancer, photocatalysis can be employed in a therapeutic technique known as Photodynamic Therapy (PDT). PDT involves the use of light-activated compounds called photosensitizers. When these compounds are exposed to a specific wavelength of light, they produce reactive oxygen species (ROS) that can kill cancer cells. The key advantage of PDT over traditional cancer treatments is its ability to target cancer cells selectively while minimizing damage to surrounding healthy tissues.
