Rose Bengal Free Acid
Rose bengal free acid is a halogenated fluorescein dye with photosensitizing properties, used diagnostically to stain devitalized cells in ophthalmology and experimentally as a photodynamic therapy agent. It generates reactive oxygen species upon light activation, inducing cell death in targeted tissues. The compound is under investigation for intralesional treatment of solid tumors.
