“…Halogen ions have long been used to promote the adsorption of analytes on the SERS substrate and enhance the SERS signal. ,, It was found that the signal-enhancing performance of the three ions, namely, Cl – , Br – , and I – , was analyte specific. ,,, Here, we first screened the three ions using their potassium and sodium salts. As shown in Figure , after mixing with 10 mM of both the potassium and sodium salts of halogen elements, the normalized absorption spectra of the Ag NPs showed red-shift bands but almost no broadening.…”

“…We found that among the halogen ions screened, chloride ions provided the best enhancement, contrary to most of the halogen-ion-assisted SERS methods. 19,22,28,29 Further analysis of the SERS spectra revealed that the malathion was closest to the Ag NP surface in the presence of Cl − , which then accounted for the best SERS signal. In addition, the hydrogen ion also contributed synergistically to the enhancement of the Raman signal of the malathion, but not by itself.…”

“…J. Xu et al, 2014). More recently, a bromide-modified AgNP for FUZD detection was proposed by W. L. Fan et al (2021), as is displayed in Figure 3d. The minimum detection concentration of the proposed SERS method for FUZD standard solution was 1 μg/L, and the detection limit of sea cucumber extracted with methylene chloride was 2 ng/g, indicating that the Ag-BrNPs-based SERS method may be a candidate approach for the rapid analysis of antibiotics sensing.…”
