Inside Back Cover: In Vivo Nitroreductase Imaging via Fluorescence and Chemical Shift Dependent ¹⁹ F NMR (Angew. Chem. Int. Ed. 50/2022)

A bimodal imaging probe FCy7-NO2 was applied to image nitroreductase overexpressed by lung cancer in vivo, as reported by Xin Zhou and co-workers in their Research Article (e202213495). Integrating two complementary imaging technologies into FCy7-NO2 enables sensitive detection of nitroreductase over a broad concentration range without tissue-depth limit.
