Textile composite wound dressing

Poly lactic acid (PLA), poly /spl epsiv/-caprolactone (PCL), and chitosan (CH) are incorporated into a biodegradable wound dressing. Physical properties of these films, including topography, water vapor permeability, degradation, and bacterial permeation as well as biological effects of toxicity on human fibroblast cells were studied. An in vivo study currently in progress is proposed.
