Cover Picture: A Rapid, Amplification‐Free, and Sensitive Diagnostic Assay for Single‐Step Multiplexed Fluorescence Detection of MicroRNA (Angew. Chem. Int. Ed. 34/2015)

The simple, sensitive, and selective detection of short‐sequence microRNAs is very challenging. In their Communication on page 10024 ff. N. Hildebrandt and co‐workers present a single‐step “mix‐and‐measure” FRET assay for the multiplexed detection of different microRNAs. The careful design of the biophotonic probe and time‐gated FRET from a luminescent Tb complex to three difference fluorescent dyes are crucial to this microRNA test for multiplexed clinical diagnostics.
