Fig. 3. (a) An SEM image of a cross-section of a hollow microvessel fiber fabricated from a microfluidic device having larger chevron dimensions. (b) Inner and outer dimensions of the hollow microvessel fiber generated. Scale bar is 50 μm. (c) and (d) SEM images of hollow microvessels showing the degree of surface finish and uniformity obtained throughout their length. Scale bar is 100 μm.
