Non-close packed photonic crystal hydrogel for glucose detection

Based on the importance of fast and non-invasive detection technology of glucose monitoring, a glucose sensor based photonic crystal hydrogel material was prepared. The phenylboric acid was the glucose recognition molecule and the three-dimensional non-close packed array was the signal transformation structure. The experimental results show that the recognition behavior of the hydrogel is shown in the form of diffraction wavelength. As the glucose concentration increases from 0 mol /L to 50 mM, the blue shift of the diffraction wavelength occurs at 10 nm, showing a good sensing property.
