innovation for industry
Although it is already used to treat certain skin cancers, photodynamic therapy cannot reach the deepest lesions. The micro needle patch patented by CEA-Leti and Inserm* overcomes this limitation. It could reach the market in 3 to 5 years.
The patch and the needles,
which take effect in just 1 hour, are made of a material that combines water, a
pharmaceutical-grade polymer and the active ingredient, explains Mathilde
Champeau, the doctoral student in charge of the project. The patch is
placed on the skin and exposed to light from LEDs emitting at 635 nm. It
dissolves in less than 1 hour. The active ingredient is metabolized by the tumoral
cells, then attacks and destroys them under the effect of the light.
