Abstract

Micro-Raman spectroscopy is employed to identify the normal and malignant human stomach cells. For the cancer cell, the reduced intensity of the Raman peak at 1250 cm^(-1) indicates that the protein secondary structure transforms from ?-sheet or disordered structures to ?-helical, while the increased intensity of the symmetric PO2 stretching vibration mode at 1094 cm^(-1) shows the increased DNA content. The ratio of the intensity at 1315 cm^(-1) to that at 1340 cm^(-1) reduces from 1.8 for the normal cell to 1.1 for the cancer cell in the course of canceration, and the ratio of the intensity at 1655 cm^(-1) to that at 1450 cm^(-1) increases from 1.00 for the cancer cell to 1.26 for the normal cell which indicates that the canceration of stomach cell may induce saturation of the lipid chain.
