Versatility of gas‐shearing for the production of microspheres. Note that the SED, the nitrogen flow, and the flow rate of the polymer solution were identical in all the experiments. a) Schematic illustration of the ionic crosslinking (using thiamine pyrophosphate) of CS aqueous droplets into CS microspheres. b) Schematic illustration of the solvent exchange process resulting in PAN, CA, EC, PCL, CAP, and PU microparticles. c) The diameter of the obtained microspheres. The scale bars in panel a) and b) are 400 µm.
