Figure 3. Assessing the effects of PEG4MAL MW and concentration on diffusive properties of hydrogel shell.

Figure 3

A) Release of 75kDa rhodamine-dextran (red) from capsules of varying polymer composition. Fluorescein-labeled PEG (green) is used to visualize B) Fluorescence intensity of capsules over time. Dotted lines represent ± 1 SD from measured capsules (n=5). C) Bulk storage modulus was used to estimate a characteristic mesh size for each capsule condition (n=3). Scale bar = 500 μm.
