| description | MXenes are a class of two-dimensional materials exhibiting excellent surface-enhanced Raman scattering (SERS) performance. Currently, the SERS studies of MXenes have been primarily focused on those with M<sub>2</sub>X and M<sub>3</sub>X<sub>2</sub> structural motifs. In order to expand the SERS sensing application based on MXenes, in this paper, a SERS sensor made of Ta<sub>4</sub>C<sub>3</sub>@AgNP nanocomposite material was fabricated by electrostatic self-assembly. Tests such as different concentrations of R6G probe molecules showed that the minimum detection limit of this SERS sensor was 10<sup>−8</sup> M, demonstrating excellent sensitivity. When different test areas are selected, the relative error of intensity under the same wave number is less than 10.7%, showing good repeatability and consistency. Furthermore, the Ta<sub>4</sub>C<sub>3</sub>@AgNP nanocomposite SERS sensor was used to detect the pesticide Ziram, and a quantitative model was established. Application detection indicates that this sensor has good sensitivity for the pesticide Ziram, and the minimum detection limit was 10<sup>−6</sup> M, which exceeded national standard requirements. The findings of this study have potential application value in the fields of food safety and environmental protection. |
