G-quadruplex is an alternative DNA motif with a special four-stranded structure and that has shown great application potential in molecular biology,biomedicine,analytical chemistry and DNA computing.[1] Since G-quadruplex can dramatically enhance the catalytic ability of hemin and fluorescence of some porphyrin derivatives,it has been widely used as signal amplifier in various biosensors.

With the increase of environmental pollutants,the safe of agricultural production has raised serious public concern for the abuse of pesticides,such as organophosphorus(OP)pesticides[1].
In this work,a one-pot signal amplified strategy was constructed based on generating hemin/G-quadruplex horseradish peroxidase-mimicking DNAzyme as the color product for the detection of the DNA seque
