The vibration characterization of NPs is typically studied by FT‐IR and Raman spectroscopies. These techniques are the most evolved and feasible compared to other simple analytical methods. The critical range for NPs is the fingerprint region, which provides the details for the material signature. In one sample, Pt‐NP (1.7 nm) functionalization and its interaction with the alumina substrate were analysed using FT‐IR and XPS techniques. FT‐IR confirms the functionality as it showed signature vibrational peaks of carboxylated C–O 2033 cm⁻¹, in addition to a broader O–H peak of 3280 cm⁻¹, respectively [54, 55]. Because of its signal‐enhancing capability via SPR phenomenon, recently improved surface‐enhanced Raman spectroscopy (SERS) is emerging as a vibrational conforming tool [56, 57].
