(Figure Presented) Excitonic interaction was utilized to design a highly sensitive in-stem molecular beacon (ISMB) in which both a fluorophore and a quencher on D-threoninols are incorporated as a pseudo base pair (see scheme; optimized combination with Cy3 and modified Methyl Red). Minimization of the difference between λmax of the fluorophore and quencher maximized quenching efficiency. © 2010 Wiley-VCH Verlag GmbH S. Co. KCaA Weinheim. Source

In the presence of poly(l-lysine)-graft-dextran, an in-stem molecular beacon involving three perylene-anthraquinone pairs in the stem region had a signal/background ratio of as high as 570. Response speed was also remarkable; equilibrium was attained within 5 minutes after addition of substrate DNA at 20°C. © 2012 The Royal Society of Chemistry. Source
