Raman spectroscopy has strong potential for providing non-invasion diagnosis of cancers.In this paper, miero-Raman spectroscopy is used to diagnose one most common liver cancer,hepatocellular carcinoma (HCC).The statistical analyzes,including t-test,principal component analysis(PCA),and linear discrim- inant analysis(LDA),are performed on the Raman spectra of malignant and normal hepatoeytes.The t-test-LDA results show that the 786-and 1004-cm~(-1)bands of the malignant and normal hepatocytes are significantly different,and PCA-LDA results show an overall accuracy of 100% for the Raman spectro- scopic identification of normal and malignant hepatocytes in our experiment.
