    摘要： Disclosed herein are customizable kits of parts for the fabrication of polymer fibers. In some embodiments, the kits provided herein comprise a scaffold comprising first and second opposite surfaces and one or more pores extending through the first and second surfaces, wherein each pore comprises a first channel and a first conjunction interface. The kits additionally comprise a plurality of nozzles, wherein each nozzle comprises a second channel and a second conjunction interface, and wherein the second interface can be removably and stably coupled to the first conjunction interface of each pore while allowing a fluid through the first channel and the second channel. The kits further comprise a plurality of closure structures, wherein each closure structure comprises a third conjunction interface, and wherein the third interface can be removably and stably coupled to the first conjunction interface of each pore to seal the pore. In some embodiments, at least the second channel of each nozzle has an internal diameter configured to allow formation of a fiber.

    摘要： Disclosed herein are nanofiber structures, and methods of making and using the same. In some embodiments, provided is a porous sheet comprising a plurality of nanofibers in contact with a supporting structure comprising a plurality of supporting elements, wherein: the nanofibers have an average diameter of about 10-900 nm; the supporting elements have an average thickness less than, about equal to, or greater than that of the thickness of the nanofibers; the sheet has an average thickness that is about 75%-150% of an average thickness of the supporting elements; a total volume of the nanofibers is less than about 20% of a total volume of the porous sheet; and/or a total volume of the supporting structure is less than about 50% of the total volume of the porous sheet. In some embodiments, provided is a multilayer structure comprising one or more sections, where each section independently comprises one or more porous sheets as described herein.
