Question 4Temoporfin (Foscan) is a photosensitizer used in photodynamic therapy for the treatment ofsquamous cell carcinoma of the head and neck. The prodrug is not being activated by internalenzymes but activated by light as an external stimulus. What is the benefit of this design?O To achieve spatiotemporal control of the killing of cancer cells.O More bioorthogonal as it does not introduce addition chemicals into the body.O To only target superficial cancer cells within the penetration depth of light.O More convenient for patients as they can activate foscan by staying in the sun.
