Abstract
Disclosed is a treated material including a base material such as an extrudate, a woven fabric, or unwoven fibers, a disperse dye-type molecule such as a dye or antibiotic dispersed within and non-covalently adhered to the base material, and a molecule-of-interest immobilized on the base material by way of a reactive group on the disperse dye-type molecule. Also disclosed are methods of producing the treated material.
Claims7
A treated material comprising:
- (a) a base material selected from the group consisting of an extrudate, an unwoven fabric, and a woven fabric, and said base material is made from at least one polymer selected from the group consisting of polyethylene terephthalate, nylon, polyurethane, polytetrafluoroethylene, polyglycolic acid, monoacetate of polyglycolic acid, triacetate of polyglycolic acid, aramid, vinylidene polymer plastics, and mixtures thereof;
- (b) a disperse dye molecule having at least a portion embedded within and non-covalently adhered to said base material, said dye molecule comprising an anthraquinone dye which has a reactive group;
- and
- (c) a molecule-of-interest comprising a peptide, immobilized on said base material by way of said reactive group of said dye molecule, said molecule-of-interest retaining its activity when immobilized,
- said treated material having the activity of said molecule-of-interest.
