Figure 4

(a) Schematic representation of one-way size-control mechanism by temperature change. (b) Optical microscopy images of gelatin-based microscrews swelling in response to temperature change. (c) Swelling kinetics of gelatin-based microscrews in PBS. (d) Swelling kinetics of different sizes of gelatin microscrews in response to temperature. (e) Effect of the laser power on the cross-linking and swelling of gelatin-based microscrews.
