The Pb2+-binding aptamer (PBA) and Hg2+-binding (HBA) have been widely adopted as biosensing elements for lead ion (Pb2+) mercury (Hg2+), due to the formation of stable specific Pb2+-G-quadruplex T-Hg2+-T structures. However, currently developed electrochemical sensors are only applicable single-point determination Pb2+ or Hg2+. Herein, a dual signal interface was realized by in-situ grafting tags (Melamine-Cu2+ complex Nile blue) bearing different redox potentials on terminal PBA HBA that...
