Flash Photodynamic Therapy – How the Saturation of Photosensitizer Absorption Enables Selective and Deeper Tumor Treatments

Advanced Science, Volume 13, Issue 1, 5 January 2026.
FLASH‐PDT uses strongly‐absorbing photosensitizers and pulsed lasers to saturate the photosensitizer absorption at ≈1‐cm tissue depths. This allows for the generation of [ROS] above the necrosis threshold level for tumors, while maintaining [ROS] in peritumoral tissues below that threshold, even when the tumor‐to‐peritumoral tissue ratio is as low as 2.

Photodynamic therapy of spontaneous animal tumors using the active component of hematoporphyrin derivative (DHE) as photosensitizing drug : clinical results

, 1987
Photodynamic therapy was performed on 25 primary spontaneous tumors in dogs and cats. The animals were injected with 2.5 mg/kg body wt. of tumor localizing fraction of hematoporphyrin derivative and treated 48 h later with laser light at 631 nm.
