(A) CV of different CPE/BSA electrodes immediately after being soaked in p-nitrophenyl phosphate substrate solution (2 mg in CBS, 5 mL): Curve (a) fully modified CPE (containing the P. pachyrhizi soybean rust spores (German source), the aptamer, and the AP enzyme). Curve (b) CPE that does not include the soybean rust spores (modified only with aptamer and enzyme). Curve (c) clean CPE/BSA. Scan rate, 100 mV·s–1. Curve (d) Fully modified CPE (containing the P. pachyrhizi soybean rust spores (Brazilian-source), the aptamer, and the AP enzyme) (B) Expanded dotted area of (A).
