Rapid Trace Detection of Pesticide Residues on Tomato by Surface-Enhanced Raman Spectroscopy and Flexible Tapes

Figure 2

(a) the simulated molecular structure. Raman spectra of (b) thiabendazole, (c) carbendazim, and (d) chlorpyrifos. The blue line represents the density functional theory (DFT)-calculated Raman spectra of the pesticide. The red line represents Raman spectra of the pesticide solid. The black line represented SERS spectra of the pesticide solution.
