Intrinsically bactericidal absorbent dressing and method of fabrication
First Claim
Patent Images
1. An intrinsically antimicrobial material comprising:
- an absorbent polymeric matrix having an enhanced surface area;
wherein said enhanced surface area further comprises a polymer of antimicrobial monomeric moieties attached to said matrix via non-siloxane covalent chemical bonds so as to result in a structure which is less prone to degradation by acids or bases produced during bacterial growth and consequent detachment of said polymer of antimicrobial monomeric moieties from the matrix, whereby the material remains antimicrobial after exposure of the material to skin or aqueous biological fluids.
