FIG. 1.

Effect of diameter on scaffold mechanical properties. (A) Nano- and microfiber scaffolds (scanning electron microscopy, 0.8 kV, 2000×). (B) Fiber diameter (n=3) increased with solution viscosity (n=4). (C) Effect of fiber diameter on scaffold tensile properties (n=6). “#” indicates significant difference within a group at consecutive values of fiber diameter and “*” indicates significant difference as compared to 320 nm at p<0.05. Red circles indicate points of measurements. PLGA, poly(d,l-lactide-co-glycolide); UTS, ultimate tensile strength. Color images available online at www.liebertpub.com/tea
