2 results about "Phoxim" patented technology

The application discloses a COF-based nanoscale enzyme and a preparation method thereof, a COF-based nanoscale enzyme sensor and a detection method of phoxim residues, and relates to the technical field of pesticide detection. The technical scheme in the application designs a COF-based nanoscale enzyme sensor and a method for detecting phoxim residues by using the sensor. The COF-based nanoscale enzyme sensor in the application is synergistically designed by valine functionalization and MnO2 nanoscale enzyme loading, provides rich recognition sites and catalytic active centers, significantly promotes interface electron transfer, and thus amplifies the detection signal. In addition, a machine learning module is introduced in the detection method, which can accurately analyze complex electrochemical signals, effectively distinguish target signals from interference noise, significantly improve the accuracy, reproducibility and anti-interference ability of detection, and provide a universal solution for rapid detection of various samples and multiple targets.
