3D simulation results for 3% chitosan microtube generation at the flow rates of 3, 4, and 5 mL/hr (PBS) and 5 mL/hr (chitosan pre-polymer solution); (a) concentration (mol/m3) profile (yellow: chitosan and light green: PBS), (b) velocity (m/s) profile, (c) chitosan concentration at the cross-section of microtube outlet, and (d) velocity of the flowing liquids at the end of outlet as a function of structure radius and PBS flow rate.
