Back Cover: An Activatable Lanthanide Luminescent Probe for Time‐Gated Detection of Nitroreductase in Live Bacteria (Angew. Chem. Int. Ed. 22/2020)

The illumination of bacterial pathogens by a specific lanthanide luminescent turn-on probe is described by H.-Y. Hu, M. Nazaré, and co-workers in their Communication on page 8512. A non-fluorescent caged precursor is intracellularly activated by bacterial nitroreductase (NTR) to form a sensitizing, light-harvesting antenna. Entrapment of the probe inside bacterial cells allows for precise localization of live bacteria by fluorescence lifetime...
