Photodynamic inactivation of viral and bacterial blood contaminants with halogenated coumarin and furocoumarin sensitizers

摘要

Viral, bacterial and parasitic contaminants in biological compositions are photodynamically inactivated by mixing halogenated coumarin and furocoumarin photosensitizers with the biological composition and irradiating the mixture. The figure depicts the proposed energy diagram of the instant photosensitizers.
