Figure 1: Schematic illustration of electrospinning devices and scanning electron microscope observation of nanofibers characteristics in lattice-like electrospun scaffolds. (a) Schematic diagram of electrospun scaffold device showed lattice-like fibers collecting by copper wire grid. (b) Picture of scaffold showed general view of lattice-like PLLA meshes. ((c), (e), and (f)) Micrographs showed nanofibers distribution in different regions of lattice-like PLLA meshes. Detailed view showed local enlarged fibers on ridge (e) and nonwoven region (f) of each lattice. (d) Histogram showed distribution of nanofibers’ diameter in scaffolds.
