Slide 0: The natural blueprint for Photo Dynamic Therapy for cancer.

Session 02: Photosynthesis – The Natural Blueprint for PDT
Good morning, I am Dr. David Comyn. Today, I am continuing our series on Photodynamic Therapy (PDT) for the treatment of cancer. In our last session, I introduced PDT as an alternative treatment that is non-toxic and minimally invasive.
Today, I want to explore how the natural phenomenon of photosynthesis provides the blueprint for Photodynamic Therapy. Photosynthesis is perhaps the most important natural process on our planet; without it, there would be no life on Earth—no plants, no animals, and no insects.
Photosynthesis is based on the ability of leaves to harness energy from the sun to absorb carbon dioxide from the atmosphere, along with water and nitrogen from the soil, to create carbohydrates, proteins, and oils. A vital byproduct of this process is oxygen—the very oxygen we breathe.
Inside the leaf, a green pigment called chlorophyll is contained within small organelles called chloroplasts. Photodynamic Therapy utilizes a similar process. When a photosensitizer (a derivative of chlorophyll) inside a cancer cell is exposed to laser light at a specific wavelength in the near-infrared spectrum, it releases a highly reactive form of oxygen known as “singlet oxygen” or Reactive Oxygen Species (ROS).
This singlet oxygen is unstable and immediately seeks to stabilize itself by reacting with vital structures within the cancer cell, effectively destroying it. Crucially, this process does not occur in healthy cells in the way we practice PDT, a topic we will explore in a future session.
In our next session, we will explore photosensitizers in more detail—how they are obtained and how they are administered. Until next time.
