(A) Dark-field optical micrograph and (B) SEM image of uniaxially aligned PVP nanofibers collected on top of the gap formed between two silicon stripes. (C) Optical micrograph of a grid formed by stacking two layers of uniaxially aligned PVP nanofibers (with their long axes rotated by 90°). (D) SEM image of a simple device structure that was directly fabricated by transferring SnO₂ nanofibers onto the same substrate to form a 2 × 4 array of crossbar junctions.(E) Photograph of a scaffold comprised of radially aligned PCL nanofibers deposited on a ring, and (F) SEM image of the radially aligned nanofibers in the scaffold.
