Figure 2

HydroCoil device. Top left: Prehydration image shows initial profile (0.014 inches). Highly compact hydrogel material was wrapped around a platinum coil (black arrow). Indentations between platinum helical coils could be seen through the hydrogel polymer. The other images are posthydration images of the system soaked in rat serum at different time points, which show marked expansion of the hydrogel polymer, which had become translucent. The outer edges of the hydrogel are denoted by white arrows. (Scale bars: 200 μm.)
