An electrochemical biosensor for the detection of Pb.sup.2+ based on G-quadruplex DNA and gold nanoparticles

We present a novel simple strategy for the detection of Pb.sup.2+ based on G-quadruplex DNA and gold nanoparticles. First, gold nanoparticles were chemically adsorbed onto the surface of a thiol-modified gold electrode. Subsequently, the substrate DNA1 was adsorbed onto the surfaces of the gold nano...
