Control over hydrogel porosity. (A) Representative confocal images (left) and corresponding quantification (right) of hydrogel void fractions and pore diameters over time (Day 0-7; 2.5 wt%; 25% modified Ad-HA). Wall thinning and pore merging, proposed to contribute to restructuring, is indicated (▼). Pore features were dependent on polymer concentration (B; Day 3; 1.25-10.0 wt%; 25% modified Ad-HA), including with change in Ad-HA modification (C; Day 3; 1.25-10 wt%; 50% modified Ad-HA). (mean ± SD; n ≥ 4; p < 0.05 for 25% vs 50% modified Ad-HA for pore diameter (*) and void fraction (#))
