Two-dimensional array Debye ring diffraction protein recognition sensing

Abstract

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.
