Abstract: A cell culture device is provided. A cell culture device according to an exemplary embodiment of the present invention comprises: a housing which has a plurality of through-holes formed through at least one surface thereof to allow carbon dioxide to be introduced thereinto from the outside and includes an inner space filled with a medium for culturing cells; a plurality of supporters which are arranged in the inner space in multiple steps while being spaced at an interval from each other so as to culture cells and are provided in a plate-shape having a predetermined area; and a porous member which is attached to one surface of the housing so as to cover the plurality of through-holes, prevents the medium filled in the inner space from leaking to the outside, and allows carbon dioxide to be introduced into the inner space from the outside.

Abstract: Provided is a filter medium. A filter medium according to an embodiment of the present invention comprises: a first porous support body which has been electrostatically treated; and a nanofiber web which is disposed on one surface of the first support body and formed by accumulating nanofibers. Accordingly, excellent air filtering efficiency is obtained even for fine dust of PM 2.5 or below, and furthermore, deterioration in air filtering efficiency may be prevented or minimized even when usage is extended for a long period of time. Therefore, the filter medium and the composite filter according to an embodiment of the present invention can be widely utilized as media of filters for various air filtering devices.

Abstract: An antiviral fabric including a fabric and an antiviral coating layer which is provided in the fabric and which includes an antiviral fusion protein having an antiviral motif bound to an adhesive protein. The antiviral fabric has excellent processability that enables simple implementation of the antiviral coating layer even on the curved surface of a fiber, the porous surface of a fabric, or a recessed or protruding surface. In addition, the antiviral fabric can have activity persistence that enable maintenance of antiviral activity for a long time without losing the same according to a condition during preparation, storage, use and washing, while having adhesion persistence that enables the maintenance of an adhesive state for a long time after the antiviral coating layer is formed on the surface thereof, and thus can be widely applied to various articles for which fabric is used.

Abstract: A yarn including a plurality of twists formed by twisting single fiber strand or multiple fiber strands; and fiber grooves, which are spaces formed between the twists, to provide three-dimensional growth spaces and migration paths for cells. Accordingly, a cell proliferation rate and cell viability may be enhanced by creating microenvironments suitable for migration, proliferation and differentiation of cultured cells. In addition, cell clusters having more uniform shapes may be easily implemented by forming the proliferation spaces and migration paths for the cultured cells as similar as possible to each other in each scaffold. Further, the cells cultured thereby can be cultured in a suitable shape and structure to be applied to an in vitro experimental model or transplanted into the body of an animal, and can be widely applied in various products used in a cell culture or tissue engineering field.
