Photosensitizing proteins for antibacterial photodynamic inactivation [PDF]

, 2020
We review recent applications of water-soluble proteins as carriers for photosensitizing molecules in antimicrobial photodynamic therapy (aPDT). The low water solubility of photosensitizers and their tendency to aggregate often impair their photophysics,
