Description
Hemostatic Effect
The specific mechanism of action of chitosan remains undiscovered but data suggest about three possible way to control bleeding:
- Sorption of plasma
- erythrocytes coagulation
- platelet adhesion, aggregation and activation
Hydron (H+) Reinforced Chitosan: Chitosan with enhanced positive charge
Converts amino group (-NH2) in chitosan fiber molecular chain to positively charged amino group (-NH3+)
Chitosan with enhanced positive charge has more enhanced performance than before.
