| titleOfInvention | Preparation method of ratiometric electrochemical aptamer sensor for simultaneously detecting aflatoxin B1 and ochratoxin A |
| abstract | The invention belongs to the technical field of electrochemical sensing, and relates to a preparation method of a ratio electrochemical aptamer sensor for simultaneously detecting AFB1 and OTA; the sensor was prepared by sequentially assembling AQ-hDNA, Fc-Apt1 and MB-Apt2 on gold electrodes, and binding of the target to the aptamer caused Fc-Apt1 and MB-Apt2 to peel off from the electrode surface, resulting in a ratio signal I Fc /I AQ And I MB /I AQ The AFB1 and the OTA are quantized and detected respectively; the linear range of detection of the sensor to AFB1 is 10pg/mL-3ng/mL, and the detection limit is 3.3 pg/mL; the detection linear range of the OTA is 30pg/mL-10ng/mL, and the detection limit is 10.0 pg/mL; and 2 substances are detected simultaneously, and the method has the characteristics of high sensitivity, good selectivity, high precision and the like. |
