| titleOfInvention | Preparation method of nano-gold coffee ring and application of nano-gold coffee ring in SERS detection |
| abstract | The invention relates to the technical field of food safety detection, and provides a preparation method of a nano-gold coffee ring and application of the nano-gold coffee ring in SERS detection. According to the invention, the nanogold coffee ring is prepared by using nanogold sol, the reducing agent in the nanogold sol is removed by washing the nanogold sol, the coffee ring with uniform and neat edges can be prepared, and the intensity of a Raman signal can be remarkably improved by using the nanogold coffee ring prepared by the invention as an SERS substrate. The example results show that when the nano-gold coffee ring prepared by the method is used as an SERS substrate to detect rhodamine 6G, the detection limit is as low as 5 multiplied by 10 ‑ 8 M, illustrates that the nano-gold coffee ring of the invention can be used as an SERS substrate for detecting trace analytes. |
