title: Cation identity dependence of crown ether photonic crystal Pb2+ sensing
ispublished: pub

abstract: We quantitatively modeled the volume phase transition of a hydrogel containing a crystalline colloidal array with a crown ether ligand which binds Pb2+. The hydrogel volume response and the wavelength diffracted depend on the Pb2+ concentration and on both the ionic strength and the valence of the nonbinding ionic species. We successfully modeled the response of this hydrogel Pb2+ sensor to ionic strength and the cation valence of the added salts. [Figure not available: see fulltext.]. © Springer-Verlag 2007.
