Abstract:
DNA has been widely investigated as a carrier for drug delivery. Here, we describe a macroscopic DNA film that has been generated enzymatically. This DNA film was subsequently coated with thrombin (TB) using an aptamer-protein interaction, to expedite hemostasis over a large area. The DNA film coated with TB (DNA patch) significantly improved plasma hemostasis by acting as a coagulative scaffold for TB, as well as carrying localized TB. This study elucidates the benefits of using enzymatic amplification-based DNA structures in the context of topical drug treatment.

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
