The invention discloses a gel material prepared from arsenic-containing solid waste as well as a preparation method and application of the gel material. The gel material prepared from the arsenic-containing solid waste is prepared by taking the arsenic-containing solid waste and waste residues as raw materials through the steps of ultrasonic oil bath, iron-containing phase lifting and sintering. The problems that the arsenic adsorption effect in sewage is poor, arsenic is difficult to remove, the treatment difficulty is large, the cost is high, a large amount of arsenic-containing solid waste in the environment cannot be treated, the environment is polluted due to stockpiling and the like are solved, meanwhile, the arsenic-containing solid waste is utilized to form a binding material to serve as a base body, the solid waste is utilized, and waste is treated with waste.

The invention discloses a method for pesticide detection by using a three-dimensional pedometer based on magnetic spherical nucleic acid. The method comprises the following steps: (1) preparing phospholipid-coated Fe3O4NPs; (2) preparing target responsive double-stranded (ds) DNA (Deoxyribose Nucleic Acid); (3) preparing Fe3O4 (at) dsDNA (deoxyribonucleic acid); (4) preparing resonance type spherical nucleic acid; (5) preparing Fe3O4 (at) T-DNA (deoxyribonucleic acid); (6) preparing a nano compound; and (7) adding exonuclease III into the nano-composite obtained in the step (6) to construct a three-dimensional walker, and detecting the content of the pesticide in the vegetables by monitoring the change of the fluorescence intensity between 488 nm and 510 nm. The method is simple to operate, low in detection cost, high in sensitivity and low in signal-to-noise ratio.
