Optimization of the photodynamic inactivation of prions by a phthalocyanine photosensitizer: The crucial involvement of singlet oxygen

Prion disorders are fatal neurodegenerative diseases caused by the autocatalytic conversion of a natively occurring prion protein (PrPC) into its misfolded infectious form (PrPTSE). The proven resistance of PrPTSE to common disinfection procedures increases the risk of prion transmission in medic...
