It is of particular importance to develop an effective method that possesses several merits simultaneously rapid, ultrasensitive, portable, and on-site detection potential for food safety detection. Herein, we propose a clickase-mediated immunoassay based on nanopore bionic signal labels the ricin. The introduction Cu/Cys clickase effectively addressed inherent limitations natural enzymes colorimetric output, respectively. Using this method, can be easily formed through DNA Gram-positive bacterial cell wall terminal peptide fragments (labeled by alkynyl azide, respectively) vancomycin. Translocation D-P@vancomycin generated highly specific oscillation current traces. This showed great superior analytical performance owing combination specificity antibodies, high CuAAC click reaction catalytic efficiency clickase, ultrasensitivity nanopore, resolution D-P@vancomycin. Moreover, practical applicability established was also verified, achieving limit (LOD) down 200.9 ag/mL with wide linear relationship under optimized conditions. In conclusion, promising
