In this study, we present an intelligent electromagnetic-actuated microfluidic chip integrated with a G-quadruplex DNAzyme-based biocatalysis platform for rapid and sensitive tetracycline (TC) detection. sensing system, TC significantly quenches fluorescent magnetic carbon dots (M-CDs) via the internal filtration effect dynamic quenching (the excitation emission wavelength at 350 440 nm, respectively). Then, on M-CDs-Aptamer is exposed bound hemin to form hemin-G-quadruplex DNAzyme, catalyzing conversion of 3,3',5,5'-tetramethylbenzidine produce blue color. This enables fluorescence/colorimetric detection TC. Importantly, automatic electromagnet-integrated was designed control shuttling materials in each function slot according programmed sequence. Under optimal conditions, limits fluorescence colorimetric methods were 11 43 μmol/L, respectively. The results tilapia (Oreochromis nilotica) comparable those traditional high-performance liquid chromatography. offers excellent performance determination potential portable, trace pollutants food environment.
