The reversible variation in the observed stop band of a hydrogel-encapsulated crystalline colloidal array was achieved through the selective formation and destruction of -S-Pb-S- linkages within the hydrogel. A reversible 45nm stop band shift could be achieved with a cyclical treatment of Pb 2+ and then dithiothreitol solution. © 2012 Elsevier Inc..
