Structural switching aptamer-based electrochemical sensor for mycotoxin patulin detection

A fluorescence aptamer sensor utilizing WS2 nanosheets for sensitive detection of patulin: enhanced specificity and wide applicability

“…The limit of detection (LOD), calculated using 3 σ ( σ = S 0 / S ; S 0 , the standard deviation of the blank sample; S , the slope of the calibration curve), was determined to be 0.23 ng mL −1 . Furthermore, the analytical performance of the FL aptamer sensor was benchmarked against other reported 43–45 sensors, as outlined in Table 2. This comparison revealed that our FL aptamer sensor exhibited greater sensitivity for PAT detection than other systems.…”
