Sponges with Janus Character from Nanocellulose: Preparation and Applications in the Treatment of Hemorrhagic Wounds

The development of a rapid and effective hemostatic dressing is highly desired in the treatment of hemorrhagic wounds. In this study, sponges with Janus character are developed using cellulose nanofibers (CNFs) that exhibit materials facets of different wettability characteristics using heterogeneous mixing and freeze−drying. The bonding of the interface between the hydrophilic and hydrophobic facets is achieved by using interpenetrating...
