摘要：
The invention relates to hemostatic compositions and methods for promoting hemostasis. The invention also relates to hemostatic compositions and methods for promoting wound healing. In various embodiments, the hemostatic compositions comprise crosslinkable collagen molecules having a porosity controlled by the ratio of weight percent collagen solids to weight percent crosslinker when crosslinking the collagen. In other embodiments, the hemostatic compositions comprise crosslinkable collagen molecules having a porosity controlled by the temperature and rate of freezing when drying the composition during fabrication. In some embodiments, the compositions contain additional agents, including biological agents.
