The drying process for microgels (A-B) involves 1:1 incubation in lyophilization medium. (C) Lyo-microgels can then be rehydrated to achieve water-swollen microgels. Microgels fabricated with PEG-NB were lyophilized in water and 70% IPA. Representative images for non-lyophilized (Non-lyo) as well as lyo-microgels for water and 70% IPA conditions shown as (D) maximum intensity projections (scale bar = 100 μm). and (E) single Z-slices from the original Z-stack with intensity profiles measured across the microgels plotted in (F) for each condition. Microgels fabricated with HA-NB were lyophilized in water and 70% IPA. Representative images for non-lyophilized (Non-lyo) as well as lyophilized microgels for water and 70% IPA conditions shown as (G) maximum intensity projections (scale bar = 100 μm). and (H) single Z-slices from the original Z-stack with intensity profiles measured across the microgels plotted in (I) for each condition.
