Abstract (en)

[origin: WO9639816A1] Viral and bacterial contaminants present in biological solutions are inactivated by mixing one of a novel class of photosensitizer with said solution and irradiating the mixture. Quinoline and quinolone compounds are useful as photosensitizers in this method. With certain photosensitizers a blocking agent may also be employed.
