Importantly, even with this high signal enhancement, the locations of the measured characteristic Raman peaks of glucose molecules agree well with those of the ground truth (while each Raman peak has a different chemical enhancement), which is attributed to the high biocompatibility and photothermal ...
The bi-molecular probe technology of 4-sulfydryl phenylboronic acid and 4-cyano phenylboronic acid is adopted, thereby achieving specific detection of glucose. The characteristic Raman peaks of 4-cyano phenylboronic acid are located at a biological silence region, thereby effectively preventing ...
c Intensity shifts of three characteristic peaks for NADH and glucose were tracked along the trajectory and show a specific pattern when crossing the infarct border and entering the ischemic heart region. Grey ribbons are 0.95 confidence intervals. d–f Intensity alterations in a sham-operated heart...
(Table2). They found that their Raman images had similar characteristic peaks with the known spectra measured from pure chemicals. For example, the spectra of cytoplasm and synthetic actin are highly similar, while major differences can be seen at 1003cm−1−1phenylalanine peak, 1081 and ...
For example, in-situ electrochemistry [123] and pressure [124] analysis were executed with Raman spectroscopy [125,126]. The fact to appreciate is that, various factors affect the position of peaks, as well as the composition of the material, size of flake [127], orientation of flake, and...
Algorithms based on empirically selected peak intensities, ratios of peak intensities and a combination of principal component analysis for data reduction and Fisher discriminant analysis for classification were investigated. Spectral peaks were tentatively identified from measured spectra of potential ...

A Raman spectroscopy method can quickly and accurately measure the concentration of ofloxacin in solution. This method has the advantages of accuracy and rapidity over traditional detection methods. However, the manual analysis methods for the collected Raman spectral data often ignore the nonlinear chara...
glucose are referred to as H and D media, respectively. The 0.5 h spectrum consists of three distinct spectral windows: the intense, broad C–H stretching Raman band (2800–3000 cm−1); a “silent region” with no prominent peaks (1800–2700 cm−1); and the so-called fingerprint ...
(1340 cm−1) without P-GERTs. All solid curves in paneleare Gaussian fitting to the data. The fitted peaks show the Gaussian (top) or Poisson (middle and bottom) distribution of the data. For Poisson distribution, the red, black, green and orange peaks reflect the probability to ...
