	abstract = "A pulsed tunable dye laser has been used to obtain the emission spectra and fluorescence decay curves of solid UO<SUP>2+</SUP><SUB>2</SUB>-<I>Datura innoxia</I> and a series of UO<SUP>2+</SUP><SUB>2</SUB>-containing complexes at liquid nitrogen temperature. The decay curves of UO<SUP>2+</SUP><SUB>2</SUB>-<I>Datura</I> exhibited a bi-exponential decay, suggesting that at least two different binding sites are present on the walls of nonliving <I>D. innoxia</I> cells. The model solutions containing carboxyl, amine, hydroxyl, phosphoryl, sulfate, and sulfonate functionalities have been utilized to identify the functionalities involving in the binding of UO<SUP>2+</SUP><SUB>2</SUB> to nonliving <I>D. innoxia</I> cell walls. Phosphoryl and dicarboxyl groups have beer demonstrated to be the dominant functional groups responsible for the binding of uranyl ions on <I>D. innoxia</I> cell walls.",
