(A) The responses of interference. (a) 1.0 ng∙mL⁻¹ DXM, (b) 1.0 ng∙mL⁻¹ DXM + 100 ng∙mL⁻¹ BSA, (c) 1.0 ng∙mL⁻¹ DXM + 100 ng∙mL⁻¹ glucose, (d) 1.0 ng∙mL⁻¹ DXM + 100 ng∙mL⁻¹ aflatoxin M1, (e) 1.0 ng∙mL⁻¹ DXM + 100 ng∙mL⁻¹ ochratoxin A. (B) Time based photocurrent response of the immunosensor repeated every 10 s under several on/off irradiation cycles for 300 s.
