5 cm-1) D-peak intensity (stars, right-hand axis) as a functionof AFM deflection voltage (lower x axis) and estimated strain(upper x axis). The integrated peak intensities were normalized to theSi peak intensity for each spectrum. Figure 6. (a) G-mode peak positions as a function of ...
The Raman gain spectrum depends on the fiber composition and temperature, but in general the Raman gain increases approximately linearly from zero at the pump wavelength to a peak at about 450/cm (i.e., approximately 50 nm at 1.06 μm) on the long wavelength side of the pump. Because of...
but were assessed by k-means to be most similar to healthy spectra. The results were the same for all 3 feature sets (FP, HW, and FPHW). Spectrum s5 was also obtained from a region assessed as 100% infiltrated with tumor tissue by ...
The Raman spectrum shows peak features that have been observed in a previous report29, and the symmetries of the peaks can be assigned as aforementioned. Raman spectral peaks in the higher energy regime (>800 cm−1) have been suggested to be related to the elementary excitations of OO35...
In another work, upon carrying out PCA and LDA on the recorded Raman spectrum from the serum samples of the patients, the diagnostic sensitivity of 91.4% and a specificity of 83% was obtained for hepatitis B virus detection (Lu et al., 2018). The peak corresponding to L-arginine found...

aTypical Raman spectrum of liver tissue slices in the range of 2000–3400 cm−1(purple line); the Raman spectra of pure protein (blue line) and lipids (yellow line) are also resolved by the SMCR algorithm. The Raman peak at 2930 cm−1(arrow 3) is related to protein, and peak...
Raman spectrum as a benchmark and compare intensities of the test sample to the known Raman spectrum. This is different from the standard procedures of ref.21where the samples have certified fluorescence spectra when illuminated by a single, specific laser wavelength. The fluorescence peak covers ...
