Construction of the SERS substrate of AgNPs modified with N-acetyl-L-cysteine and ZnO for sensitive detection of acephate

Key Points

• Detection of acephate demonstrated high sensitivity with the modified SERS substrate.
• The substrate combined AgNPs with n-acetyl-l-cysteine and ZnO for optimal performance.
• Construction involved specialized treatments to enhance surface-enhanced Raman scattering (SERS) signals.
• This approach highlights the potential for using novel substrates in pesticide detection.
