1. A method of inhibiting growth of viruses, comprising:
- attaching an effective amount of a dye, selected from one of reactive dyes and dyes containing reactive functional groups, onto a substrate, said composition of said dye being further characterized by having the ability to absorb light in a predetermined spectrum and intensity range to thereby produce singlet oxygen in the presence of an oxygen containing atmosphere, upon absorption of light in said predetermined spectrum range, in an amount effective to inactivate viruses when in contact therewith; and
contacting viruses to be inactivated with said substrate having said composition adhered thereto in the presence of oxygen and light in said predetermined spectrum and intensity range.

Abstract
A method of inactivating viruses, articles for inactivating viruses and methods of manufacture of such articles are disclosed. Singlet oxygen generating dyes are attached to a substrate. Upon exposure to light, singlet oxygen is generated to inactivate viruses present. In a preferred embodiment, more than one dye is used. If only one dye is used, acridine yellow G is particularly effective.

16. An article of manufacture capable of inhibiting growth of viruses comprising:
-
a substrate; and
an effective amount of a composition of a dye selected from at least one of reactive dyes and dyes containing reactive functional groups, attached to said substrate, said dye being further characterized by having the ability to absorb light in a predetermined spectrum and intensity range and to produce singlet oxygen in the presence of an oxygen containing atmosphere, upon absorption of light of said predetermined spectrum and intensity range, in an amount effective to inactivate viruses when in proximity thereto. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 43, 44, 45)
