1. A nanofiber assembly comprising:
a nanofiber film has a first planar surface and a second planar surface at an opposing side of the first planar surface, the first planar surface being free from a supporting substrate, and
at least one first nanofiber film disk on the second planar surface of the nanofiber film,
wherein the at least one first nanofiber film disk comprises a plurality of nanofibers arranged in a planar orientation and randomly oriented relative to each other, has at least one geometry shape, and forms a pattern on the nanofiber film, and
wherein the nanofiber film comprises a drawn nanofiber sheet, a filtered nanofiber film, or a combination thereof.
