FT-IR spectroscopy study on cutaneous neoplasie

In this work we report a preliminary study of Fourier transform infrared sp ectroscopy on normal and neoplastic human skin samples suffering from two k inds of cancer, namely epithelioma and basalioma. The analyzed skin samples have been drawn from different parts of the human body, after biopsies. By performing a complex band deconvolution due to the complexity of the tissu e composition, the analysis within the considered frequency region (900-400 0 cm(-1)) of the collected IR spectra, allowed us, first of all, to charact erize the presence of the pathologies and to show clear different spectral features passing from the normal tissue to the malignant one in particular within the region (1500-2000 cm(-1)) typical of the lipid bands.
