A) Overview of flow-focusing microfluidic design for creating HA–NB microgels. B) Fluorescence imaging of labeled microgels. Histograms of various independent runs demonstrate control over microgel size generation of either an average of 100 or 50 μm depending on the microfluidic design used. Mean and standard deviation as error bars are plotted for each individual run. Scale bar: 500 μm. C) Microgels can be crosslinked with PEG–Tet. The bulk storage modulus of the MAP scaffold can be tailored by annealing of microgels with PEG–Tet at various ratios. Microgels with an average 100 μm were used. D) Representative images of MAP scaffolds and average calculated percent void space.
