What Are the Limitations of ATR in Nanotechnology?
Despite its advantages, ATR is not without limitations. One of the challenges is the limited penetration depth of the evanescent wave, which might not capture the bulk properties of thicker samples. Furthermore, material interactions with infrared light can vary, potentially leading to spectral distortions. Therefore, while ATR is excellent for surface analysis, it may need to be complemented with other techniques for a comprehensive understanding of a nanomaterial's properties.
