Abstract: Provided is an antiviral filter medium. An antiviral filter medium according to one embodiment of the present invention includes a first member provided with an antiviral coating layer formed of fibers and including, on part or all of the outer surface of the fibers, an antiviral fusion protein in which an antiviral motif is bound to an adhesive protein. Accordingly, the antiviral filter medium exhibits antiviral properties, is excellent in filtration efficiency and ventilation amount (or flow rate), and has low pressure loss. In addition, the antiviral filter medium is characterized in that the coating layer exhibiting antiviral properties retains adhesiveness for a long period of time after being attached to the surface. Moreover, the antiviral filter medium can retain antiviral activity for a long time without loss of the antiviral activity due to external conditions during production, storage, and use.

Abstract: A method for manufacturing a fiber assembly for providing a binding surface to a bio-substance is provided. A fiber assembly for providing a binding surface to a bio-substance according to an embodiment of the present invention is manufactured by a method comprising the steps of: (1) preparing a fiber assembly in which a plurality of fibers is accumulated; and (2) performing modification to provide the fiber surface with a carboxyl group reactive to an amine group present in a bio-substance. According to the method, a bio-substance can be easily introduced at a high content into the fiber assembly. In addition, bio-substances that are conjugated therebetween and adsorbed through physical adsorption, etc. are remarkably reduced in the introduction procedure of bio-substances, whereby bio-substances can be availed with high precision and reliability in applications employing bio-substances. Furthermore, applications employing bio-substances can undergo minimal property variations attributed to the bio-substances as detachment of the bio-substances is minimized or prevented. Accordingly, the bio-substances fixed on the surface of the fiber assembly according to the present invention can find a broad spectrum of applications in various fields including the material engineering, bio engineering, medical fields, and so on.

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.
