Figure 4.

Figure 4

Time-dependent change in pressure relative to baseline measured by chemomechanical sensor of Figure 2 in response to cyclic change in fructose at fixed pH 7.4 and fixed ionic strength 0.16 M in 1X PBS buffer. The environmental fructose concentration, which was initially zero, was suddenly increased to 5 mM at time equal zero, suddenly reduced to zero again at time equal 1100 minutes, and then the cycle was repeated twice more (thermally-cured zwitterionic GSH, pre-gel polymer concentration 13 wt.%).
