Ovoflavin photochemical deactivation method for pathogens in biological liquid sample

The invention belongs to the technical field of deactivation of pathogens and particularly relates to an ovoflavin photochemical deactivation method for pathogens in a biological liquid sample. In view of problems in the existing ovoflavin pathogen deactivation methods, a technical scheme of the invention is as follows: the ovoflavin photochemical deactivation method for the pathogens in the biological liquid sample comprises the steps of adding ovoflavin into the biological liquid sample and irradiating the biological liquid sample with light, wherein the light is narrow-spectrum ultravioletlight in the wavelength range of 360nm-370nm and/or 390nm-400nm. According to the method, parameters such as illumination time, illumination intensity and ovoflavin concentration are further preferred. By employing the technical scheme of the invention, an excellent pathogen deactivation effect can be achieved, and the damage to other ingredients in the biological liquid sample is low. 本发明属于病原体灭活技术领域，具体涉及一种生物液体样本中病原体的核黄素光
