Abstract
A microfibrillar high molecular weight chitosan-based textile can be used as a hemostat. The chitosan has been treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan textile. A single or multiple such treatments may be employed. For example, the chitosan textile may be irradiated under nitrogen using γ-irradiation, treated under a nitrogen plasma, or both.
