Chitosan–hyaluronic acid hybrid film as a novel wound dressing: in vitro and in vivo studies

Wound dressing with high quality is a kind of highly demanded wound‐repairing products. In this article, chitosan (CS) and hyaluronic acid (HA) were used to fabricate a novel wound dressing. CS/HA composite films with high transparency could be fabricated on glass or poly(methyl methacrylate) (PMMA) substrates, but not on poly(tetrafluoroethylene) (PTFE) plate. Along with the increase of HA amount, the resulting films became rougher as detected...
