Surface Enhanced Raman Scattering (SERS) technology has great potential in detecting pesticide residues,but there are still limitations in trace and quantitative analysis. This paper proposes a pesticide detection strategy based on nano scale convex polyhedrons Au@4-ATP@Au (NCPs-Au@4-ATP@Au). XRD results showed that because of the selectivity and inductance of probe molecules to gold precursors,the crystal surface structure information of NCPs-Au@4-ATP@Au nanoparticles and spherical gold nanoparticles is significantly different,which is reflected in the strong reflection peak at (200). Combined with SEM and absorption spectrum,it can be determined that NCPs-Au@4-ATP@Au has both spherical and polyhedral structure characteristics. Compared with spherical gold nanoparticles,the absorption peak was significantly red shifted and closer to the wavelength of excited light,which was theoretically more conducive to enhancing the SERS signal. Experiments showed with NCPs-Au@4-ATP@Au,which was coated with high index crystal surface and embedded with probe molecule 4-ATP as the enhanced substrate,the Limits of detection (LODs) of Carbendazim (CBZ) reached 0.66 nmol·L-1. According to the Raman and SERS spectral shift CBZ molecules,it can be preliminarily confirmed that CBZ molecules are adsorbed to gold nanoparticles through the NH bond andCObond. Au@4-ATP@Au improved the sensitivity because of the multi-convex structure. Meanwhile,with 4-ATP as the calibration signal,the spectral stability and timeliness were also improved. After normalization,spectral stabilitys relative standard deviation (RSD) was as low as 7.03%,the signal intensity decreased by 5.87%,and RSD was 2.94% in half a month. The results showed that NCPs-Au@4-ATP@Au improved the trace and quantitative detection ability of SERS in detecting pesticides,and the substrate is expected to promote the practical application of SERS.
