Abstract
@@@@Highlights •A dual-ratiometric electrochemical aptasensor was developed to simultaneously detect two organophosphorus pesticides.•CNHs/AQ/AuNPs composites were used to generate a reference signal and enlarge response signals.•Hairpin DNA with a rigid 2D structure can improve the selectivity and reliability of the sensor.•The aptasensor can simultaneously detect malathion and omethoate with no cross-reactivity.
