By integrating iron-cobalt squarate bimetallic metal-organic framework (Fe-Co-SqBMoF) based smart material (SM) with functional DNA (fDNA), we designed a target responsive fDNA@Fe-Co-SqBMoF bioelectrode that exhibits recognition induced switchable response to serve as reagentless single step electrochemical apta-switch (REA). The construct takes advantage of fDNA ability bind and concentrate on the receptor interface, while Fe-Co-SqBMoF@SM multifeatures an immobilization matrix signal generating switch. Fe-Co-SqBMoF was introduced prepare redox active pencil graphite electrode (PGE), (aptamer) decorated PGE impart specificity selectivity. synthesis characterized through X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, micro-Raman dynamic light scattering (DLS), UV-visible (UV-vis) analysis, each decoration fabrication via field emission scanning electron microscopy (FE-SEM), static water contact angle measurements, cyclic voltammetry (CV), impedance spectroscopy (EIS). To explore potential application bioelectrode, REA for detection aflatoxin B1 (AFB1) which permitted AFB1 in linear range 0.7-1000 pg/mL LOD 0.54 pg. practical applicability demonstrated milk samples.
