Fourier Transform Infrared (FTIR) and Raman imaging offer complementary information about the spatial location of molecules within cells. In this paper we investigate the integration of both imaging modalities in an extended image containing unique FTIR and Raman spectra for each pixel. Two types of cells were investigated: red blood cells infected with the Plasmodium falciparum parasite and Micrasterias, a desmid microalgal species. The microscope configuration and pixel size were selected specifically for acquiring images with the same pixel size, and samples were fixed to a sample holder in order to measure the same cells with the same orientation. Images were first analysed individually ..
