    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: 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.
