Abstract
A light-activated antimicrobial article is disclosed, consisting essentially of an acridine dye covalently bonded without a linking group to a nylon material. The article may be made using electron beam processing. The article in combination with light absorbed by the acridine dye may be used to inhibit the growth of microorganisms. A photosensitive nylon material in which the acridine dye is disposed on the nylon material may also be used. Medical kits that include a light source and an article having the acridine dye are disclosed.
Claims11
A light-activated antimicrobial article consisting essentially of an acridine dye covalently bonded without a linking group to a nylon material.
A method of making a light-activated antimicrobial article, comprising
- providing a photosensitive nylon material consisting essentially of an acridine dye disposed on a nylon material, and
- processing the photosensitive nylon material using an electron beam such that the acridine dye is covalently bonded without a linking group to the nylon material.
A method for inhibiting the growth of microorganisms, comprising
- providing a photosensitive nylon material consisting essentially of an acridine dye disposed on a nylon material,
- exposing the photosensitive nylon material to a microorganism,
- providing a light source, and
- activating the light source such light emitted by the light source is absorbed by the acridine dye.
A method for inhibiting the growth of microorganisms, comprising
- providing a light-activated antimicrobial article comprising an acridine dye covalently bonded without a linking group to a nylon material,
- exposing the light-activated antimicrobial article to a microorganism,
- providing a light source, and
- activating the light source such that light emitted by the light source is absorbed by the acridine dye.
A medical kit comprising:
- a light source, and
- a light-activated antimicrobial article consisting essentially of an acridine dye covalently bonded without a linking group to a nylon material.
