ding author Christoph Krafft, PhD, of the Institute of Photonic Technology, Jena, Germany explains: 'The principle of our implementation of wavelength-modulated Raman spectroscopy is that fluorescence emission, ambient light, and system transmission function do not significantly vary, whereas the Raman signals do vary upon multiple wavelength excitation with small wavelength shifts. In turn this leads us to 'cleanly' extract the Raman signature even in the presence of such factors. In the current work, we developed a hardware-based approach to suppress confounding factors in Raman spectra that requires a minimum of pre-processing and offers further unsurpassed advantages."

Editor-in-Chief of Biomedical Spectroscopy and Imaging, Parvez Haris, CChem, FRSC, FRSPH, adds: "This work represents a significant step beyond current Raman microscopy that breaks completely new ground. Raman analysis for biomedicine is at a crucial juncture where there is worldwide recognition that it is on the verge of potential acceptance by the wider community and clinical practice if key issues, such as the ones the authors have raised, can be overcome.

"The straightforward nature of the technique means that biologists and researchers at the life sciences interface can benefit immediately from the advantages of the novel method," he concludes.
