Abstract

The present invention relates to methods and compositions for wound healing. In particular, the present invention relates to promoting and enhancing wound healing by utilizing cross-linker covalent modification molecules to attach and deliver wound active agents to a wound. In addition, the present invention provides methods and compositions utilizing oppositely charged polyelectrolytes to form a polyelectrolyte layer on a wound surface. The invention further relates to incorporating wound active agents into a polyelectrolyte layer for delivery to a wound.

Claims (4)

1. An article comprising: a polyelectrolyte multilayer formed from anionic and cationic polymers and being from 1 to 500 nm thick disposed on a support selected from the group consisting of a wound dressing and a biologic wound dressing, said polymer multilayer having a releasable antimicrobial silver composition incorporated therein, wherein said releasable antimicrobial silver composition is releasable in an amount of from 0.05 to 0.5 μg/cm 2 of said polymer multilayer per day.

2. A kit comprising the article of claim 1 .

3. The article of claim 1 , wherein said article is packaged in a sterile package.

4. The article of claim 1 , wherein said article does not substantially impair the healing of wounds.
