SERS has been extensively used to enhance the signals from biomolecules, but it requires the development of specific SERS substrates and/or functionalized metallic nanoparticles [49,50]. However, the transfer of the Raman spectral library, such as those available in FTIR analyses, remains a major challenge that stands in the way of clinical translation for Raman-based technologies, and continued effort is needed to facilitate the transition from benchtop to bedside by developing novel experimental designs and structured protocols for the objective method. In MFS, Raman bands at 345-450, 575, 750, 973 and 1070 cm-1 are associated with various Si-O-Si . The Raman intensity depends on the intensity of the laser source as well as the polarizability and concentration of the molecules in the samples [3].

The following band assignment is therefore based on this evidence as well as on classical textbooks on vibrational assignments 5, 36, 37 and the literature published previously on similar compounds. However, Raman imaging experiments require the acquisition of many thousands of spectra and, typically, total acquisition times for these, depending on the desired spectral quality, would be in the order of a few minutes to several hours. Chem. Additional bands, which are apparently E2 modes, are observed at 308 and 676 cm1 at a sample temperature of 50C and at 389 and 741 cm1 at a sample temperature of 130C that are not observed in samples at room temperature.

Therefore, the application of RM can be used as a non-invasive method for the early diagnosis of cancer cells. The methodology developed allowed for unprecedented chemical characterization of fluorescently labeled biological tissues in vivo [54]. Am. & Ozaki, Y.) The bottleneck of many applications of Raman spectroscopy on biological materials is the interpretation of the spectra and assigning molecular structures to individual bands.
