Figure 1

At the point where the laser beam is focused, the hydrogel contracts, the microstructures bend, and the cell’s attachment points to the microstructure tips will be displaced by several microns. Note that since the cell is not attached to the contracting gel, it is positioned away from the heated gel region.
