Researchers develop injectable bandage

Eurekalert  April 2, 2018
Researchers at Texas A&M used thickening agent known as kappa-carrageenan, obtained from seaweed, to design injectable hydrogels simulating the structure of human tissues. When kappa-carrageenan is mixed with clay-based nanoparticles, injectable gelatin is obtained. The charged characteristics of clay-based nanoparticles provide hemostatic ability to the hydrogels. Specifically, plasma protein and platelets form blood adsorption on the gel surface and trigger a blood clotting cascade. These bandages can show a prolonged release of therapeutics that can be used to heal the wound…read more. TECHNICAL ARTICLE
