A process of coating a medical device surface with peptide-based nanoparticles with antimicrobial and healing properties; a process to coat a polyurethane (PU) dressing with a cross-linkable polymer adhesive in which was immobilized LL37 peptide conjugated-gold (Au) nanoparticles (LL37NPs) suitable to be applied on wounds. by following the steps of: 1) preparation of medical device surface; 2) coating the surface with a cross-linkable polymer adhesive; 3) spreading of peptide-based nanoparticles over the surface coated with the photo cross-linkable polymer adhesive; 4) exposing the surface coated with the adhesive and the nanoparticles to UV light; 5) placing the surface in phosphate buffer to leach loosely bound nanoparticles. The process described herein may be employed in the production of wound dressings, bandages, PU catheters and medical tubings.

A system for treating a tissue site includes a reduced-pressure source to apply reduced pressure, a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site, and a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape includes an adhesive layer for sealing the drape to the tissue site to create a sealed space having the manifold therein, and a non-adhesive layer formed from a portion of the adhesive layer. A method for manufacturing a medical drape includes providing a sheet of adhesive material and treating a side of the sheet of adhesive material to form a non-adhesive layer and an adhesive layer. The method laminates a release liner adjacent the adhesive layer.
