Rose Bengal
Photosensitive Dye
Rose Bengal is a water-soluble photosensitive dye exhibiting significant antibacterial activity through both dark-state and light-activated mechanisms. It demonstrates lethal photodynamic effects against S. carlsbergensis under aerobic light conditions while also inhibiting the growth of S. aureus in the dark. Furthermore, Rose Bengal restricts colony size in filamentous fungi and suppresses the growth of diffusive fungi. This compound is valuable for research related to infections and photodynamic therapy applications.
