Abstract
Blood clotting is vital for preventing bleeding after an injury. Hemostasis is a complex cascade involving numerous plasma proteins. Uncontrolled bleeding leads to mortality. The presence of Ca (calcium) activates and promotes the different phases in the coagulation cascade. Even nonbiological surfaces such as silicates may activate coagulation factor XII (FXII). This causes the clotting of the blood. The exceptional hemostatic ability of the mesoporous calcium-decorated silica nanoparticles (MCSNs) is achieved by stimulating the factors needed to form fibrin mesh, a durable clot, thereby establishing hemostasis. This may be used as a hemostatic agent during an accident surgical procedure and other bleeding-related trauma conditions. This study investigates the mechanistic activation of the coagulation cascade by MCSN through blood coagulation index, clotting time, and coagulation activation studies like PT and aPTT. Our finding demonstrates that MCSN induces platelet adhesion and RBC aggregation and activates thrombin generation through distinct pathways.
