Abstract

In the presence of poly(L-lysine)-graft-dextran, an in-stem molecular beacon involving three peryleneanthraquinone 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.
