Figure 3. Model protein release.

Figure 3

BSA release from the PEG-dinorbornene hydrogel was observed over approximately 10 days, where ~ 90% of the BSA is released within 48 hours. While 1 mg of BSA per sample was loaded, approximately 0.82 mg on average was recovered (Minf). BSA release was evalulated by fitting a Fickian diffusion coefficient to the release curve (Deff ~ 1.4 × 10-8 cm2/s; open squares data; solid line predicted release based on Fickian fit). This release profile is substantially slower than Fickian diffusion of BSA in aqueous solution (Do ~ 1 × 10-7 cm2/s; dashed line predicted Fickian diffusion in water).
