Abstract

image

A volume resetting agent is incorporated into a boronic acid functionalized hydrogel containing an embedded photonic crystal, yielding a glucose sensor material with a linear and fast response, minimal hysteresis, and good stability under simulated physiological conditions. The hydrogel can be tuned to modulate both the sensitivity and kinetics.
