The invention relates to a surface-imprinted combined modified electrode and its production method, comprising a novel chalcone-substituted cyclotriphosphazene (CBRG-Fe) and multi-walled carbon nanotube (MWCNT) composite, intended to be used as an electrochemically active sensor for the sensitive determination of ractopamine.

This invention discloses a three-dimensional multilayer sheet-like nanozyme, its preparation method, and its application in the immunochromatographic detection of small molecule environmental pollutants, belonging to the field of nanozyme and immunochromatographic detection technology. The three-dimensional sheet-like nanozyme is meticulously designed by continuously constructing Au nanoparticles (NPs) and AuPt bimetallic NPs on flexible graphene oxide (GO) nanosheets. Beneficial effects: In the nanozyme, two-dimensional GO provides a large surface area and high stability, hundreds of large AuNPs provide enhanced colorimetric ability and a large spherical surface area, and tens of thousands of AuPt satellites act as spatial catalytic sites and produce excellent peroxidase-like activity. The proposed bimodal ICA can simultaneously detect three important drugs, namely gentamicin, clenbuterol, and ractopamine, in real complex samples, greatly improving the detection performance of existing colorimetric ICA techniques based on simple catalysis, thus showing great application potential in real-time monitoring of small molecule targets under different conditions.
