Thiazole Orange as a Fluorescent Light-Up Probe for the i-Motif and its Application to the Development of a Molecular Logic System

摘要

Thiazole orange (TO) as a fluorescent probe for H+-induced i-motif formation is reported. TO fluoresces in the presence of the folded structures of i-motif DNA sequences and H+ and/or Ag+ ions, which allows the design of an "OR" logic gate.
