Abstract
The present invention is appertaining to a water-soluble photosensitive composition of photodynamic environmental disinfection and method of environmental disinfection by using the same. In this method, a short-term atomization step and a white light irradiation step with a low light dose are performed on the water-soluble photosensitive composition composed of water, low-concentration methylene blue and hydrogen peroxide to obtain photoactivated atomized particles, which can be performed in a sequential or simultaneous manner. The obtained photoactivated atomized particles can effectively inhibit the pathogenicity and/or the infectivity of viruses in the environment, and therefore, be applied to the method of photodynamic environmental disinfection.
