The invention discloses preparation of a nano-enzyme / biological enzyme cascade composite material based on DNA tweezers driving and application of the nano-enzyme / biological enzyme cascade composite material in on-site rapid detection of metolcarb. The copper-based nano enzyme with the nanoflower structure, which is synthesized from copper sulfate and DNA (Deoxyribonucleic Acid) at room temperature, shows excellent laccase-imitating activity and stability; according to the base complementary pairing principle and the high affinity of an aptamer to a molecular target, DNA tweezers fix AChE on the surface of nano-enzyme to form a CuNFs-Apt-AChE cascade enzyme composite material. The output signal of the sensing system is further enhanced through the synergistic effect of the enzyme cascade system, so that the detection sensitivity is improved. Sodium alginate hydrogel is used for fixing a CuNFs-Apt-AChE cascade enzyme composite material, and a high-stability immediate response platform for detecting meta-tolcarb residues is prepared. The sensor shows good sensitivity, portability and stability in practical application, and an innovative platform is provided for on-site rapid detection.

This invention relates to the field of environmental functional materials technology, specifically to a method for preparing a nitrogen-doped bimetallic biochar adsorbent and its application. The method uses grape pomace as biomass raw material, which is pretreated with HCl via hydrothermal treatment, then mixed with KOH, urea, and a bimetallic source solution. The nitrogen-doped bimetallic biochar adsorbent is prepared by oxygen-limited pyrolysis carbonization. The nitrogen-doped bimetallic biochar adsorbent prepared by this invention possesses high specific surface area, hierarchical porous structure, and magnetic separation characteristics. It exhibits excellent adsorption and removal effects on the carbamate pesticides methomyl and pirimicarb in water, with maximum adsorption capacities reaching 50.97 mg·g⁻¹, respectively. ‑1 and 159.50 mg·g ‑1 It exhibits good anti-interference ability and stability in complex aquatic environments and can be used for the treatment of pesticide-polluted water bodies.
