With enrichment of tetracycline (TC) in ecosystems, its accurate detection has become a major concern. Noble‐metal nano‐particles have attracted great interest as potential materials for sensing applications because their remarkable electrical properties and adaptability. Herein, novel electro‐chemical technique based on carbon nano‐tubes (CNTs) the support material is developed to detect TC with high precision. To achieve characteristic response TC, composite electrode prepared by loading platinum–gold (PtAu) CNTs surface via electro‐deposition. The oxidation peak at 0.38 V used signal probe draw standard curve comparing intensities peaks various concentrations. PtAu‐CNTs/GCE sensor exhibits sensitivity (LOD = 1.05 × 10−8 mol/L) anti‐interference properties. This study demonstrates complex environments.
