Abstract
A method of inactivating viruses comprises bringing the viruses into contact with an effective amount of a photosensitizing agent which will bind to the viruses and/or virus infected cells, and then exposing the resulting mixture to visible light to excite and inactivate the viruses.
Claims5
The method of inactivating an enveloped virus which comprises first bringing said enveloped virus into contact with an effective amount of a photosensitizing agent to inactivate said virus, said agent being a merocyanine dye which selectively binds to said virus and then exposing the combination of the virus and agent to visible light of sufficient strength for a sufficient period of time to photosensitize and inactive the virus.
A method of inactivating an enveloped vircus without affecting its usefulness in making a vaccine whyich comprises bringing the virus into contact with an effective amount of a merocyanine dye photosensitizing agent to inactivate the virus and then subjecting the virus and photosensitizing agent to an effective amount of visible light for a sufficient length of time to inactivate the virus without affecting its usefulness in making a vaccine.
A method treating a disease which is caused by an enveloped virus, which disease results in lesions, said method comprising forming a combination of the enveloped virus in the lesions and an effective amount of a merocyanine dye photosensitizing agent to inactivate the virus and then exposing the combination to an effective amount of visible light for a sufficient length of time to inactivate said virus.
