Photodynamic inactivation of poliovirus

Virology, 1963
Abstract Poliovirus, as usually found in fluids of infected cultures, cannot be inactivated photodynamically in the presence of heterotricyclic dyes. However, if the mature virus is freed of extraneous organic material, dyes can attach to the virus and render it light-sensitive.

PHOTODYNAMIC INACTIVATION OF LYSOZYME BY EOSIN

Photochemistry and Photobiology, 1973
Abstract— It has been demonstrated that singlet oxygen is the major oxidizing entity in the photo‐dynamic inactivation of hen egg white lysozyme by eosin, using D2O to enhance the solvent‐induced decay lifetime, and azide ion as a specific scavenger.
