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.
