The present disclosure relates generally to wound inserts that may include an outer layer and an inner core of biopolymers that may be used in the therapy of tunneling wounds and for facilitating wound healing. Kits for use in practicing the methods are also provided.

The present invention provides a modified collagen comprising S-nitroso groups and a method of manufacture of such a modified collagen. Also provided is a wound dressing comprising such a modified collagen, particularly a wound dressing comprising a formulated composition comprising such a modified collagen.

The present invention provides a hemostatic porous composite sponge comprising i) a matrix of a biomaterial; and ii) one hydrophilic polymeric component comprising reactive groups wherein i) and ii) are associated with each other so that the reactivity of the polymeric component is retained, wherein associated means that said polymeric component is coated onto a surface of said matrix of a biomaterial, or said matrix is impregnated with said polymeric material, or both.

A composition, comprising a hydrogel matrix and microparticles within said matrix, said matrix comprising a cross-linkable protein and a cross-linking agent, wherein said cross-linking agent is able to cross-link said cross-linkable protein, wherein said microparticles comprise a drug.

The present disclosure provides synthetic collagen and methods of making and using synthetic collagen that include a synthetic collagen that facilitates wound closure comprising an isolated and purified triple helical backbone protein that facilitates wound closure comprising one or more alteration in a triple helical backbone protein sequence, that stabilize the isolated and purified triple helical backbone protein and does not disrupt an additional collagen ligand interaction; and one or more integrin binding motifs, wherein the isolated and purified triple helical backbone protein facilitates wound closure.

A process for the extraction of collagen from collagen-containing matter, wherein the process comprises; incubating the collagen-containing matter in an acidic solution to form an incubant, then diafiltrating the incubant to substantially purify solubilised collagen within the incubant, thereby forming a retentate, then separating the soluble and insoluble matter of the retentate to remove the remaining insoluble matter, wherein the soluble matter is a substantially pure collagen solution.

Wound dressings, methods for forming the wound dressings, and methods for using the wound dressings are described. Wound dressings include a crosslinked hydrogel matrix and a plurality of porous absorbent microspheres encapsulated in the crosslinked matrix. The hydrogel matrix and the microspheres can include the same or different hydrogel polymers, e.g., alginates or the like. The wound dressings can be used in treating chronic wounds and burn wounds and can promote autolytic debridement.
