Effect of in‐oil semi‐photocrosslinking on the size, short‐term stability at physiological temperature, and swelling of gelatin methacryloyl (GelMA) (20% wt/vol) microgels. (a) Optical images and corresponding size of GelMA microgels produced in oil using a droplet microfluidic device as a function of in‐oil photocrosslinking time. (b) Thermal stability of semi‐photocrosslinked GelMA microgels over time as a function of photocrosslinking time. The scale bars represent 200 μm. For each condition, at least 4 snapshots containing 30 microbeads each were analyzes (120 microbeads in total for each condition)
