Gelatin matrix

Gelatin matrix is a protein-derived biomaterial that functions as a physical barrier in various medical applications, particularly as a hemostatic agent. When applied to a wound site, the gelatin matrix forms a mesh-like framework that holds clotting molecules in the body to facilitate blood clot formation. The matrix expands as it absorbs blood, creating a physical structure that prevents further bleeding. Gelatin matrices not only operate as physical barriers to stop blood flow by creating a matrix for platelet adhesion but also accelerate the development of the platelet plug that forms the foundation of the fibrin clot. In hemostatic applications, gelatin is often combined with thrombin, which participates in coagulation and creates a fibrin clot while the gelatin expands to generate a tamponade effect that mechanically halts bleeding. Gelatin matrices are available in various forms including sponges, fleeces, sheets, and liquid formulations. Beyond hemostasis, gelatin-based materials are also used in tissue engineering as support structures for promoting cell proliferation and in food packaging as biodegradable materials. The physical and mechanical properties of gelatin matrices are influenced by factors such as amino acid composition, molecular weight distribution, and the ratio between different collagen components.
