Contraction flow of granular hydrogels. a) Extrusion force measurements over time for the control and adhesive granular hydrogel samples at slow (3 μL/s) and fast (9 μL/s) flow rates. b) Overview of contraction flow device, showing device dimensions (top) and fluorescently labelled granular hydrogel flowing through device (bottom). c) Representative trajectories of tracked particle position in the contraction flow device as a function of time, including representative trajectories at multiple time intervals after starting flow in the device (0 to 10 s, 10 to 20 s, and 20 to 30 s).
