RNA-templated fluorescence activation is a nucleic acid detection strategy that offers the possibility of direct visual detection of genetic information in living cells. Here we describe a new reaction strategy for fluorescence activation, in which a phosphine on one DNA probe reduces an azide group in a linker on a second probe, resulting in linker cleavage and release of a fluorescence quenching group. These “Q-STAR” probes are shown to yield a strong fluorescence turn-on signal in ca. 20 min, with very low background and substantial amplification by turnover on the template. A green/red pair of such probes allowed the discrimination of two bacterial species by a single nucleotide difference in their 16S rRNA. The beneficial properties of the reductive quencher release design makes these probes promising candidates for widespread applications in the detection of nucleic acids in vitro and in cells.
