Shear-Thinning Nanocomposite Hydrogels for the Treatment of Hemorrhage
Internal hemorrhaging is a leading cause of death after traumatic injury on the battlefield. Although several surgical approaches such as the use of fibrin glue and tissue adhesive have been commercialized to achieve hemostasis, these approaches are difficult to employ on the battlefield and cannot be used for incompressible wounds. Here, we present shear-thinning nanocomposite hydrogels compos...
متن کاملShear-thinning hydrogels for biomedical applications
Injectable hydrogels are becoming increasingly important in the fields of tissue engineering and drug delivery due to their tunable properties, controllable degradation, high water content, and the ability to deliver them in a minimally invasive manner. Shear-thinning is one promising technique for the application of injectable hydrogels, where preformed hydrogels can be injected by application...
متن کاملNanocomposite hydrogels for biomedical applications.
Hydrogels mimic native tissue microenvironment due to their porous and hydrated molecular structure. An emerging approach to reinforce polymeric hydrogels and to include multiple functionalities focuses on incorporating nanoparticles within the hydrogel network. A wide range of nanoparticles, such as carbon-based, polymeric, ceramic, and metallic nanomaterials can be integrated within the hydro...
متن کاملInjectable Shear-Thinning Hydrogels for Minimally Invasive Delivery to Infarcted Myocardium to Limit Left Ventricular Remodeling.
BACKGROUND Injectable, acellular biomaterials hold promise to limit left ventricular remodeling and heart failure precipitated by infarction through bulking or stiffening the infarct region. A material with tunable properties (eg, mechanics, degradation) that can be delivered percutaneously has not yet been demonstrated. Catheter-deliverable soft hydrogels with in vivo stiffening to enhance the...
متن کاملMethods To Assess Shear-Thinning Hydrogels for Application As Injectable Biomaterials
Injectable hydrogels have gained popularity as a vehicle for the delivery of cells, growth factors, and other molecules to localize and improve their retention at the injection site, as well as for the mechanical bulking of tissues. However, there are many factors, such as viscosity, storage and loss moduli, and injection force, to consider when evaluating hydrogels for such applications. There...
