Claim Text:
1. A method of treating a wound in a subject in need thereof, said method comprising contacting the wound with an effective amount of a re-wet biocompatible cellulose hydrogel membrane, wherein the re-wet cellulose hydrogel membrane comprises one or more properties selected from the group consisting of: a cellulose content of from about 2% to about 9% by weight; a tensile strength of from about 50 kPa to about 600 kPa; a tear strength of from about 0.10 N/mm to about 0.60 N/mm; a strain to failure of from about 40% to about 80%; a suture retention strength of from about 0.05 N/mm to about 0.30 N/mm; a transparency that exceeds 85% at 550 nm (at 100 microns thickness); a Young's modulus of from about 100 kPa to about 700 kPa; and a puncture resistance of from about 50 kPa to about 300 kPa, the re-wet biocompatible cellulose hydrogel membrane comprises a composite comprising microcrystalline cellulose and bacterial cellulose, the re-wet biocompatible cellulose hydrogel membrane further comprises one or more microcrystalline cellulose layers and one or more bacterial cellulose layers, the one or more bacterial cellulose layers are oriented closer to the wound than the one or more microcrystalline cellulose layers, and the hydrogel membrane is in the shape of a contact lens.
