Get the lead out: The title fluorescence receptor exhibits a high affinity and selectivity for Pb2+ over competing metal ions in water (see picture) with an overall emission change of approximately 8-fold at the emission maximum for Pb2+. The fluorescence receptor can remove 96 % of 100 ppb Pb2+ from human blood, and can be useful and effective for the selective and rapid removal of Pb2+ in vivo.
