A wound dressing for treating a wound, the wound dressing comprising a nitric oxide generating layer for generating nitric oxide by the acidification of a nitrite salt, wherein the nitric oxide generating layer includes a solid powder nitrite salt component and a solid proton source component, methods and uses of such a wound dressing for treating a wound.

Suspensions containing oxidic nanoparticles as a dispersed phase and an aqueous solution containing citric acid as a diluent are disclosed. Advantageously, the oxidic nanoparticles contain bioglass and ceria. Also further disclosed are topical dosage forms including such oxidic nanoparticles and uses thereof. The dosage forms were found to be useful in the treatment of wounds and post-operative lesions, and particularly for the prevention of seroma, the prevention of infections and/or the prevention of inflammation.

A hydrogel includes a polysaccharide including aldehyde groups and carboxy groups, a functionalized chitosan, and iron (III) ions. The hydrogel further includes particles including a core including a carboxy-functionalized polythiophene and a shell including polydopamine. A wound dressing includes the hydrogel and a base layer selected from the group consisting of a gauze, lint, plaster, bandage and cotton wool. The hydrogel is attached or adhered to the base layer.
