The present invention relates to a modified collagen obtainable by providing isolated collagen; freezing the isolated collagen; dehydrating the frozen collagen; and maturing the dehydrated collagen. Also disclosed are methods of preparing the modified collagen and uses thereof.

Disclosed are solid and frozen haemostatic materials and dressing's consisting essentially of a fibrinogen component and a fibrinogen activator. Also disclosed are methods of treating internal wounded tissue in a mammal by applying one or more of these haemostatic materials and dressings.

The present disclosure provides click-crosslinked hydrogels and methods of use.

The present invention provides a composite hydrogel comprising: (a) an anionic or cationic functional group-containing polymer; and (b) at least one active pharmaceutical ingredient (API), wherein the API is oppositely charged to the anionic or cationic functional group-containing polymer. Methods of displacing an active pharmaceutical ingredient from the composite hydrogel comprising a step of treating the composite hydrogel with an ion source comprising anions, cations, or a combination thereof, a plasma jet consisting of excited gas, ions, electrons and photons, wound dressings comprising the composite hydrogel and methods of treating wounds using the composite hydrogel are also provided.

Embodiments of the present disclosure pertain to a hydrogel that includes one or more galactomannans and one or more biodegradable polymers. Additional embodiments of the present disclosure pertain to absorptive hygiene products (AHPs) that include the hydrogels of the present disclosure. The AHP may include, without limitation, diapers, tampons, sanitary pads, or combinations thereof. Further embodiments of the present disclosure pertain to methods of forming the hydrogels of the present disclosure. Such methods include associating one or more galactomannans with one or more biodegradable polymers. The methods of the present disclosure may also include a step of incorporating the hydrogel as a component of an AHP.

The invention relates to an antiseptic material, in particular as a wound dressing, containing a carrier material and at least one antiseptic together with a surfactant, wherein the carrier material is equipped with a cyclodextrin or cyclodextrin derivative that is loaded in the antiseptic or antiseptics.
