Extended Data Fig. 1: Alginate microgels are roughly cell-sized.

a. Cartoon workflow for preparation of alginate microgel slurry. b. Bright-field image of microgel slurry after synthesis, with nearly transparent microgels. Scale bar = 200 µm. c. Representative images outlining workflow for quantifying microgel size. The polyanionic alginate backbone was positively stained with DAPI and segmented in Fiji to calculate particle diameter. d. Distribution of alginate microgel sizes fit to a Gaussian distribution. Data shown are mean ± SD from n = 3 separate images from 3 separate fields of view for each alginate wt% and 3 independent AMG preparations.
