The SEM-TEM, DLS, AFM and EDAX alongwith spectroscopic studies have further substantiated our observation in the same context. The quantification of bisulphate in one of its real sample through UV�Vis spectroscopy using these nanoprobes as indicator has also been carried out successfully. The Raman measurements have clearly indicated the rich SERS potential of these silver nanoresonators. � 2022 Elsevier B.V.BisulphateNanoresonatorsRaman spectroscopyReal samplesSPR bandArticlehttps://doi.org/10.1016/j.inoche.2022.109366
