Abstract
Chemically-modified quaternary-structured fiber collagens of minimum molecular length, diameter and periodicity, and containing a relatively high positive electrostatic charge are claimed as hemostatic agents. Specific examples are guanidinated, esterified, and guanidinated-esterified collagen fibers of the type described.
