The invention discloses an AFB1 colorimetric-electrochemical dual-mode detection kit based on MIL-88 (at) Pd / Pt nano-enzyme and application of the AFB1 colorimetric-electrochemical dual-mode detection kit. According to the invention, AFB1-Apt is connected to MBs through an amidation reaction. And the MIL-88 (at) Pd / Pt is connected to the cDNA through an amide reaction. And then, through DNA hybridization, the cDNA and AFB1-Apt are complementarily combined. In the presence of AFB1, it specifically binds to AFB1-Apt, resulting in double strand hybridization dissociation. After magnetic separation, NaAc-HAc, TMB and H2O2 are added to precipitate, colorless TMB is catalyzed to be oxidized into blue oxTMB through a reaction system, a colorimetric signal is generated, and the absorbance change of the oxTMB is measured. The supernate is added to the treated GCE, and the electrode is immersed in a PBS buffer solution containing H2O2. The electrochemical reduction of H2O2 generates a significant SWV signal. According to the invention, a high-performance dual-mode sensing platform is constructed, cooperative amplification and cross validation of signals are realized, and the method has the advantages of high selectivity, high sensitivity, low cost and the like.
