Abstract: A durable anti-mold packet comprises a holding pouch, an absorption material and an anti-mold evaporation substance. The holding pouch has an upper edge, a lower edge, a left edge and a right edge. The left edge and right edge are folded and overlapped to form a housing space and an overlapped seam edge. The upper edge and lower edge are pressed and sealed. The overlapped seam edge is partially pressed and sealed to form an evaporation vent communicating with the exterior. The anti-mold evaporation substance is coated onto the absorption material which is held in the housing space. Therefore a greater amount of the anti-mold evaporation substance can be absorbed by the absorption material and the anti-mold evaporation substance can be slowly released from the absorption material to increase use duration of the anti-mold packet and provide anti-mold effect for a longer period to meet use requirements.

Abstract: Biofunctionalized fibers including a fiber platform and a histidine-tagged protein and, optionally, an antibody. Chitosan is a fiber useful as the fiber platform. The fiber platform may be treated with nickel or may be directly linked to the histidine-tagged protein e.g., histidine-tagged streptococcal IgG-binding protein, protein G, protein G3T, GFP or RFP. The resulting biofunctionalized fibers can be assembled into protein fiber assemblies by a variety of biofabrication methods. The fiber assemblies, e.g., in the form of woven fabrics, are useful for (i) antigen capture; (ii) immunoanalysis, and/or (iii) multiplexed analysis. In one fabrication, each fiber of a fiber assembly presents a specific antibody, and mixing and matching of fibers, for example by weaving of fabrics from various antibody-presenting fibers, allows for multiple antigens to be captured simultaneously for multiplexed analysis.
