Figure 2. CS:PEO fibers dissolve slowly under physiologic conditions.

Figure 2

10mg samples of CS:PEO fiber blends (n=3) were immersed in 5ml of PBS at 37°C. At predetermined time points PBS was removed. Samples were then washed once with diH2O and freeze dried overnight. Mass loss approximated PEO content (A). SEM micrographs showed no major morphological changes in fibers over the degradation period (B, scale bar represents 50 µm). The average fiber diameter measured in these micrographs also showed no significant changes within individual fiber blends after hydration (C).
