title: A molecular logical switching beacon controlled by thiolated DNA signals.
abstract: A logical switching MB is established, with an "ON/OFF" switching function. In this study, thiolated DNA can participate as a switching controller to regulate the fluorescent increments of other DNA input signals. Assisted by gold nanoparticles and DNA branch migration, one and two-switch systems have been achieved.
