The present thesis evaluates the possibility of noninvasive label free imaging on living cells by means of Raman microspectroscopic mapping. Here, after Raman measurements on living cells, immunofluorescence (IF) imaging served as a reference and helped to derive spectral patterns from Raman datasets. This allowed a clear identification of five intracellular comparments.With these patterns, artificial IF images (aIF) could be generated from Raman data, which can illustrate all five organelles only from the Raman spectral data. The feasibility of Raman spectroscopy to capture specific alternations in living cells, without changing the specimen itself, make the method highly interesting for investigations in molecular pathology.
