Abstract: An embodiment of the present disclosure provides an extracellular matrix-based bioadhesive as an adhesive in the form of a composition including an extracellular matrix-containing hydrogel and a gelatin curing agent, wherein the extracellular matrix-containing hydrogel is gelatinized. Since the extracellular matrix-based bioadhesive according to an embodiment of the present disclosure has the same or similar rheological properties as gelatin, the bioadhesive has flowability at a temperature of 30° C. or higher and may be evenly and easily applied to a lesion site in the body. In addition, the extracellular matrix-based bioadhesive according to an embodiment of the present disclosure may adhere well to the lesion site because of a level of adhesive strength that is about 2 to 6 times higher than that of fibrin glue used as a commercial tissue adhesive. In addition, the extracellular matrix-based bioadhesive according to an embodiment of the present disclosure is based on a tissue-derived extracellular matrix, and thus includes a tissue-derived wound healing component or a tissue regeneration component, and may be used for wound healing or tissue regeneration in addition to bioadhesive applications.

Abstract: A two-terminal atom-based switching device having a fast operating speed and high durability and a manufacturing method thereof are disclosed. It is possible to reduce a forming voltage during positive voltage forming by forming an oxygen vacancy percolation path through negative voltage forming, which is first forming, and forming high binding energy and low formation energy between oxygen vacancies and metal ions implanted through positive voltage forming which is second forming after the negative voltage forming. Further, since a significant amount of metal ions implanted into the insulating layer through negative voltage application switching after the positive voltage forming is removed, the volatility of the two-terminal atom-based switching device may be improved, and a stuck-on failure phenomenon in the durability may be prevented.
