Smart aligned multi-layered conductive cryogels with hemostasis and breathability for coagulopathy epistaxis, nasal mucosal repair and bleeding monitoring

Yeast cell templated porous hollow silica spheres for rapid hemostasis accompanied by antibacterial action

“…Some vascular-rich organs, such as the liver and spleen, are prone to bleeding from tears, while it is difficult to stop the bleeding by suturing and compression due to the large number of blood vessels in these organs. 22 Therefore, we constructed a mouse model of severe liver injury to evaluate the hemostatic effect of Ag@HMSNs/500 in vivo , and the whole hemostatic process was recorded. The specific experimental process is shown in Fig.…”

Gelatin/calcium chloride electrospun nanofibers for rapid hemostasis

“…The operation referred to the literature. 30,31 Fifteen Kunming mice (40-45 g) for tail amputation models were divided randomly into five groups (blank, gauze, Gel membrane, Gel/ CaCl 2 (6 : 1) and Gel/CaCl 2 (5 : 1) membranes). The mice were firstly anesthetized by intraperitoneal injection of 10 wt% chloral hydrate (0.5 mL per 100 g).…”

A contact-polymerizable hemostatic powder for rapid hemostasis

“…As an alternative to some types of fluids, bandages, sponges, and dressings, a hemostatic powder represents a valuable option that is relatively easy to use and can be perfectly matched to complex wound contours and volumes. 9–11 Multiple hemostatic powders ( e.g. , silicates, chitosan, zeolites, polysaccharides, coagulation proteins, and some traditional Chinese medicines) have been developed.…”

“…As an alternative to some types of fluids, bandages, sponges, and dressings, a hemostatic powder represents a valuable option that is relatively easy to use and can be perfectly matched to complex wound contours and volumes. [9][10][11] Multiple hemostatic powders (e.g., silicates, chitosan, zeolites, polysaccharides, coagulation proteins, and some traditional Chinese medicines) have been developed. [12][13][14][15][16] However, most powders have a poor adhesive capability, partially limiting their hemostatic application, because it is hard to maintain their stability due to the dynamic movement of tissues and the effect of auxiliary pressure.…”
