Abstract
We proposed using spectroscopy-tomography of single cells as a diagnostic tool for improving early cancer detection and treatment. This technology potentially obtains the 3D distribution of cellular components at high spatial resolution. We used spectroscopy-tomography to generate and analyze a series of cross-sectional images of a borosilicate glass microsphere 10µm in diameter, easily determining the distribution of internal submicron defects in the microsphere. We also used this to estimate the 3-dimensional refractive index distribution in a single human breast cancer cell. The nucleus, which has a high refractive index, is clearly distinguishable.
