Abstract:
We report a laser-enabled fabrication strategy for the in situ integration of cobalt single-atom nanozyme (Co1-SANozyme) into N-doped carbon electrodes. The resulting electrode enables sensitive electrochemical detection of three structurally analogous neonicotinoids (NNIs)-imidacloprid (IMD), clothianidin (CLO), and thiamethoxam (THX)-at low overpotentials (-0.6 to -0.8 V). The electrode generates distinct electrochemical fingerprints for each NNI, providing a promising platform for their selective identification and monitoring.
