## Description

- description: "Tip-enhanced Raman spectroscopy (TERS) combined with principal component
    analysis (PCA) offers a robust approach for enhancing signal quality and uncovering
    spectroscopic features otherwise concealed by noise. This study demonstrates that
    integrating TERS with PCA in large-scale datasets effectively reduces noise and
    enhances the extraction of weak Raman signals that are often obscured by random
    spectral fluctuations. The methodology was applied to hyperspectral datasets acquired
    from MoSe2 monolayers exhibiting nanoscale surface features. Through this approach,
    previously hidden nano-Raman peaks were successfully isolated, enabling reliable
    chemical identification at the nanoscale. The combined use of TERS and PCA significantly
    improves sensitivity and resolution in the spectroscopic analysis of two-dimensional
    materials, advancing their characterization with respect to interfacial and environmental
    effects.\r\n"
