Diagnosis of tumors during tissue-conserving surgery with integrated autofluorescence and Raman scattering microscopy (2013)
Journal Article
Kong, K., Rowlands, C. J., Varma, S., Perkins, W., Leach, I. H., Koloydenko, A. A., …Notingher, I. (2013). Diagnosis of tumors during tissue-conserving surgery with integrated autofluorescence and Raman scattering microscopy. Proceedings of the National Academy of Sciences, 110(38), https://doi.org/10.1073/pnas.1311289110

Tissue-conserving surgery is used increasingly in cancer treatment. However, one of the main challenges in this type of surgery is the detection of tumor margins. Histopathology based on tissue sectioning and staining has been the gold standard for c...
