1. Bandages

“Electrospun dextran fibers (EDFs) are demonstrated herein to be useful as a temporary "scaffolding" to sequester and transport one or more associated substances of interest to a location of interest. A liquid solvent is present at or will be present at the location of interest, and the scaffolding is temporary because the electrospun dextran fibers dissolve upon contact with the liquid, releasing the associated substances of interest into the liquid. In one embodiment of the invention, the EDFs are fabricated into a bandage which also includes therapeutically beneficial active agents, usually bioactive agents. For example, the bandage may include substances that promote hemostasis such as thrombin and fibrinogen. In this embodiment, the thrombin and fibrinogen are present within the bandage in forms that are active upon contact with liquid such as blood. Application of the bandage to a bleeding wound results in dissolution of the dextran fibers in the liquid blood, and release of active thrombin and fibrinogen directly into the wound bed. The active thrombin rapidly catalyzes the conversion of the fibrinogen to fibrin, and formation of a hemostatic plug or clot from fibrin ensues, resulting in hemostasis.”
