International Journal of Bioprinting 3D printed topographically fabricated micron track peripheral nerve conduit

Figure 2. Microstructure and hemostatic effect of chitosan conduits. (A) 3D-printed mold with micron tracks. (B) The appearance of MTC and CC can
be seen as a difference in the inner surface. (C) Electron microscopic microstructure of MTC. (D) Stress–strain curves of MTC and CC. (E) The topology
of MTC was observed using scanning electron microscopy. The topology of MTC was observed using scanning electron microscopy and surface profile
meter. (F) The widths of MTC micropatterns were statistically analyzed based on SEM images, respectively. (G) Rat tail hemostasis experiments of MTC.
(H) Statistical results of the hemostatic response of MTC (ns = not significant, *P < 0.05, **P < 0.01).
