Objective

To establish a method for rapid determination of the aflatoxin B1 (AFB1) and zearalenone(ZEN) in Zea mays L. by molecularly imprinted-surface‑enhanced Raman spectroscopy (SERS).

Methods

Dual‑template molecularly imprinted materials were prepared and used for the pretreatment and purification of Zea mays L.. Ag nanoparticles were employed as the SERS‑active substrate, and a label‑free detection method was developed based on the characteristic SERS peaks of AFB1 and ZEN. The effects of molecularly imprinted materials preparation conditions and SERS detection parameters (including substrate concentration and type of aggregating agent)on the analytical performance were investigated.

Results

Under the optimized conditions, dual‑template molecularly imprinted materials pretreatment (template-to-monomer molar ratio of 1:2), Ag nanoparticles concentration of 0.56 mmol/L, and potassium bromide and magnesium chloride as aggregating agents for AFB1 and ZEN, respectively. The limits of detection were 1.5 ng/mL for AFB1 and 5.0 ng/mL for ZEN. The linear ranges for both toxins were 10–1000 ng/mL, with determination coefficients of 0.9268 for AFB1 and 0.9611 for ZEN. The average recoveries ranged from 93.29% to 96.10%, and the relative standard deviations were all below 5%.

Conclusion

The established method is simple, rapid, accurate, and suitable for on‑site rapid screening of AFB1 and ZEN in Zea mays L. powder.
