A vector control composite system and methods for producing a vector control strategy capable of blocking mosquito host-seeking cues for reducing the transmission of mosquito-borne diseases. The vector control composite system comprises a substrate coated with a composition further comprising nanoparticles functionalized to block thermal, vibrational, or gray body energy emission of an emitter, thus interfering with mosquito infrared receptor functions for host-seeking. The vector control composite system may comprise a base substrate coated with an IR ceramic coating having an insulation component, a multispectral signature mitigation component, an IR anti-reflective component, whereby the multispectral signature mitigation component and IR anti-reflective component contain functionalized nanoparticles. Embodiments of the vector control composite system may be incorporated in various textiles used as nets, garments, tents, and equipment.

Described herein is an antiviral face mask and methods of use thereof to inactivate a virus in contact with the face mask. The face mask may include a fibrous material with silicon nitride powder impregnated therein and a layer surrounding the fibrous material. In some embodiments, silicon nitride is present in the fibrous material at a concentration of about 1 wt. % to about 15 wt. %.

A temporary tattooing ink is produced from concentrated genipin. In one embodiment, the concentrated genipin forms part of a solution. In another embodiment, the genipin is provided in a gel form which also includes a solvent and a thickening agent. Finally, an applicator is described into which genipin may be embedded for applying to a user's skin.

Expanded, nanofiber structures are provided as well as methods of use thereof and methods of making.

The method of the present invention for making a BNNT fabric comprises dispersing Boron-Nitride nanotubes at loading greater than 5 weight % in an electrospinning delivery solution; electrospinning the delivery solution onto a collector thereby forming a mat comprised of BNNT-PAN nano fibers; and, finally removing any electrospinning delivery solution from the mat leaving a fabric of intertwined Boron-Nitride nanotubes.

Provided are nanowire-coated fibers and compositions comprising one or more nanowire-coated fibers and methods of making the fibers and compositions. The fibers can be organic or inorganic fibers. The nanowires can be metallic or semiconducting nanowires. The nanowires are disposed on at least a portion of a surface of a fiber or fibers. The fibers and compositions can be used as barcodes (e.g., for anti-counterfeiting methods). The fibers and compositions also can be used as photodetectors (e.g., methods of detecting electromagnetic radiation).
