Figure 2. Structural morphologies of hydrogels with or without microparticles.

Figure 2

(A) SEM images of DextranVS-PEG4SH hydrogels with different degree of substitutions (DS) and w/v percent of DextranVS and PEG4SH. Top panel represents hydrogel without embedded microparticles and bottom panel represents hydrogels with microparticles (white arrows). (B) SEM images of PEGDA-PEG4SH hydrogels with 10X10Y composition. Microparticles deposited as layers in the hydrogel matrix as indicated by solid arrows.
