Fig. 3. Sensitivity of the ARNs based AFB1 detection method. (A) Luminescence signal of different concentration of AFB1. The concentrations of AFB1 from the 1 to 7 are 0 pM, 1 pM, 10 pM, 100 pM, 1 nM, 10 nM and 30 nM, respectively. Luminescence intensity are shown as the 30 minutes values. (B) Linear relationship between the luminescence intensity and the logarithm of the AFB1 concentration.
