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. L'invention concerne une maille comprenant des nanofibres de polysaccharide oxydé et un polymère formant des fibres. Le polysaccharide oxydé est dispersé de manière uniforme sous forme de molécules et/ou de nanoparticules dans une matrice du polymère formant des fibres. Le polysaccharide oxydé peut être l'acide polyanhydroglucuronique ou un de ses sels ou complexes intermoléculaires. Le polymère peut être le PVA. La maille peut être utilisée dans des pansements. Le pansement peut comporter de multiples couches.
