METHOD FOR INACTIVATION OF MICROORGANISMS USING PHOTOSENSITIZERS

摘要

Methods and apparatuses for treating fluids to inactivate microorganisms whi ch may be present therein, said fluid containing one or more components selecte d from the group consisting of protein, blood and blood constituents are provided. The methods comprise adjusting the percentage of plasma in said fluid to a desired value; mixing an inactivation-effective, substantially no n- toxic amount of an endogenous photosensitizer or endogenously-based derivati ve photosensitizer to said fluid; exposing said fluid to photoradiation of sufficient wavelength and energy to activate the photosensitizer, whereby sa id microorganisms are inactivated.
