摘要

We attach 2-D colloidal arrays onto the surface of hydrogels containing biotin. The hydrogel volume shrinks with increasing concentrations of avidin due to the formation of avidin-biotin crosslinks. This causes the Debye diffraction ring diameter to increase, and the 2-D diffraction wavelength to blue-shift.
