Abstract: Provided is yarn for a cell culture scaffold. The yarn for a cell culture scaffold according to an exemplary embodiment of the present invention includes slitting yarn produced by cutting a compressed nanofiber web to a predetermined width. Accordingly, by creating microenvironments suitable for migration, proliferation and differentiation of cells, cell viability may be enhanced and cells may be three-dimensionally proliferated. In addition, a scaffold according to the present invention has a mechanical strength sufficient for prevention of disruption of the scaffold which occurs during cell culture, such that cells may be stably proliferated. Further, the scaffold according to the present invention uses slitting yarn formed of the compressed nanofiber web, thereby having pores with various sizes, and therefore cell proliferation and cell viability may be enhanced by creation of an extracellular matrix-like environment.

IPC: C12M1/12
Abstract: Provided is a cell culture sheet for a large-capacity incubator. A cell culture sheet according to one embodiment of the present invention is a cell culture sheet provided in a large-capacity incubator having a plurality of sheets disposed to be spaced apart at predetermined intervals therein, wherein the cell culture sheet has an area of 100 cm2 or more and a bending depth of 0.5 cm or less. As such, even when the culture sheets are closely placed in a limited volume of space, there is little sagging or shape deformation in a specific direction to prevent the occurrence of contact with adjacent culture sheets, thereby preventing a decrease in cell culture volume due to a dead space. Furthermore, since the flow of a cell culture fluid due to the occurrence of contact can be minimized or prevented, a large capacity of cells can be stably and smoothly cultivated such that the cell culture sheet is very suitable for a large-capacity incubator and can be widely applied to the cell culture industry.

Abstract: A thermally adhesive fiber web implemented by including the steps of: (1) preparing respectively a first spinning solution in which a support component and a second spinning solution in which a thermally adhesive component; (2) performing electrospinning such that the first spinning solution is discharged to a portion of the end surface of a discharge port and the second spinning solution is discharged to the remaining portion, thereby accumulating side-by-side type thermally adhesive composite fibers having a diameter of less than 1 μm; and (3) applying heat to the accumulated side-by-side type thermally adhesive composite fibers. The thermally adhesive fiber web enables easy interfacial bonding to a heterogeneous material with a different material and structural specification and prevents pores formed in an initial stage from being closed during thermal bonding.

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.
