Non‐nucleosidic chromophores in the stem of a molecular beacon inhibit excimer fluorescence through the formation of a donor–acceptor complex (see picture). The excellent reduction of the background fluorescence allows the detection of DNA and RNA targets in the presence of a significant excess of the probe.
