Implanted Miniature Light Devices for Phototherapeutics

Advanced Therapeutics, Volume 9, Issue 1, January 2026.
Modern phototherapeutics has many attractive features; however, the shallow penetration of light into skin and tissue is an inherent physical limitation that restricts usage to superficial sites of disease. To mitigate this major problem, researchers and clinicians are actively developing miniature implanted light devices that can be implanted within a

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.

Basic research on the biology of meta-tetra(hydroxyphenyl) chlorin for photodynamic therapy in gynaecology: Somatic genotoxicity assayed with Drosophila melanogaster [PDF]

, 2018
The well-established SMART test, a somatic mutation and recombination assay of Drosophila, was applied to assess the possible genotoxicity of sublethal meta-tetra(hydroxyphenyl) chlorin (mTHPC) photodynamic therapy (PDT) to clonogenic cells in situ.
