The Raman spectroscopy measurements performed by Ferrari et al. showed that the 2D peak intensity in the single layer graphene was four times higher than the intensity of G peak. The intensity of G peak in both bulk graphite and single layer graphene was found to be comparable. However, its...
PEAK-PRESERVING AND ENHANCING BASELINE CORRECTION METHODS FOR RAMAN SPECTROSCOPYBaseline correction in Raman spectroscopy is a procedure that eliminates/reduces the background signals generated by residual Rayleigh scattering or fluorescence. Provided is a novel baseline correction procedure called the Iterative...
The QE65000-Raman Spectrometer is a great option for low-light level Raman spectroscopy. The TE-cooled (down to -15 °C) detector features low noise and low dark signal, which enables low-light-level detection and long integration times (analogous to the shutter speed of a camera) from 8...

Raman micro-spectroscopy, also known as micro-Raman spectroscopy, Raman microscopy, or Raman microanalysis, involves the coupling of a Raman spectrometer to a confocal microscope, enabling chemical analysis of samples with sub-micron spatial resolution (Fig. 1A). ...
In this regard, surface-enhanced Raman spectroscopy can detect molecular species in complex mixtures on the basis only of their intrinsic and unique vibrational signatures7. However, the development of surface-enhanced Raman spectroscopy for this purpose has been challenging so far because of ...
We speculated that surface enhanced Raman spectroscopy (SERS) might be an ideal technique for detecting the sxRNA bound protein with a high degree of sensitivity and specificity. With this long-term goal in mind, we first developed the two-step process described here for the simple detection of...
Confocal Raman micro-spectroscopy RS was performed on an inverted confocal Raman microscope (Alpha 300 M+, WITec GmbH, Germany) equipped with a 532 nm laser (WITec GmbH, Germany) and a 785 nm single mode diode laser (XTRA II; Toptica Photonics Inc., USA). The output signal was ...
Raman spectroscopy has made a positive impact as a process analytical and control tool for pharmaceutical manufacturing and bioprocessing, with demonstrated scientific and financial benefits throughout a product’s lifecycle.Similar content being viewed by others The role of Raman spectroscopy in ...
To exhibit these attributes, Raman spectroscopy was applied to a typical biotechnology process: the fermentation of glucose with yeast. This was conducted using a 785 nm Raman spectrometer attached to a dip probe introduced to the fermentation mixture. The resulting set of Raman spectra were analyzed...
