A quencher‐free linear probe composed of serinol nucleic acid (SNA) with a fluorescent uracil analogue (PeU) can selectively light‐up a target RNA. In the single‐stranded state, a flexible SNA scaffold (yellow strand) facilitates the quenching of monomer emission by aggregation of PeU residues. Upon the formation of a duplex with the target RNA (white strand), the PeU is separated by base pairs, resulting in “light‐up” detection with high sensitivity. This linear probe also discriminated a fully matched RNA strand from a single‐base mismatch. More information can be found in the full paper by H. Asanuma and K. Murayama on page 120 in Issue 1, 2020 (DOI: 10.1002/cbic.201900498).
