“…[4][5][6] Cherry tomatoes are preferred as a garnish in salads, but some illegal merchants usually abuse 2,4-D on cherry tomatoes to make them premature. The EU food pesticide residue regulation states that the maximum residual level for 2,4-D in cherry tomatoes is 0.05 mg kg -1.7 Thus, it is crucial and essential to investigate analytical techniques with high sensitivity for the quick and precise identification of 2,4-D residues.Pesticide residue detection technologies have traditionally relied on chromatography, such as highperformance liquid chromatography (HPLC), 8,9 liquid chromatography-mass spectrometry (LC-MS), 10,11 gas chromatography (GC), 12,13 and enzyme-linked immunosorbent assay (ELISA). 14,15 These techniques, however, are time-consuming and sophisticated, necessitating extensive sample processing procedures and specialized staff to operate.…”

The residual 2,4‐dichlorophenoxyacetic acid (2,4‐D) in fruits poses a serious threat to human health. The continuous deposition of 2,4‐D in the body may cause symptoms such as cancer or Alzheimer's disease, therefore, it is of great significance for the detection of 2,4‐D traces on fruits. In this paper, we proposed a simple “paste‐collect‐test” strategy based on surface‐enhanced Raman spectroscopy via tape sampling (SERS‐tape sampling). The flexibility and stickiness of commercial tapes were combined with the excellent activity of optimized silver nanoparticles (Ag NPs) for rapid trace detection of pesticides in cherry tomatoes. The first two steps of “paste” and “collect” were completed by the tape to simplify the sampling procedure of the analyte molecules, and the “test” step was accomplished by deposing Ag NPs on the surface of the tape after analyte collection. The whole process was completed in a few minutes. The results showed that the limit of detection (LOD) of 2,4‐D in cherry tomatoes was 3.63 × 10−10 M with the SERS‐tape sampling approach, which is much lower than the maximum residue limit specified by the European Union (EU). This simple and easy‐to‐operate method is highly sensitive and could be a promise of 2,4‐D for food safety.
