Abstract

A mesh comprises nanofibers of oxidised polysaccharide and a fibre-forming polymer. The oxidised polysaccharide is uniformly dispersed in the form of molecules and/or nanoparticles in a matrix of the fibre-forming polymer. The oxidised polysaccharide may be polyanhydroglucuronic acid or salts or intermolecular complexes thereof. The polymer may be PVA. The mesh may be used in wound dressings. The dressing may have multiple layers.
