Abstract
Hemostatic wound dressings that include cationic polymers and related hydrogels, methods for making and using the wound dressings.
Claims30
A wound dressing, comprising a cationic polymer comprising:
- (a) polymer backbone;
- (b) a plurality of cationic centers, each cationic center covalently coupled to the polymer backbone by a first linker;
- (c) a counter ion associated with each cationic center;
- and
- (d) a hydrolyzable group covalently coupled to each cationic center through a second linker, wherein the hydrolyzable group is hydrolyzable to an anionic center to provide a zwitterionic polymer having the anionic center covalently coupled to the cationic center through the second linker.
