Construction of nanocomposite-enhanced electrochemical sensor based on DAFB-DCTP/AuNPs/CNNs for the sensitive simultaneous detection of Pb(II), Cu(II) and Cd(II) in food

Key Points

• The sensor enables sensitive simultaneous detection of multiple heavy metals in food products.
• With a detection limit in the low nanomolar range, it shows effective monitoring capabilities.
• Constructed using DAFB-DCTP, AuNPs, and CNNs, it represents a novel nanocomposite approach.
• These findings support the need for advanced monitoring techniques to ensure food safety from toxic heavy metals.
