Terahertz spectroscopic characterization of cancer cells

摘要

This work presents the first demonstration of the characterization of cancer cells using Fourier Transform Infrared Spectroscopy (FTIR) technique in the low terahertz frequency range of 10-25 cm~(-1) and shows how this technique can be used to discriminate between two types of cancer (prostate and bladder) in cell culture. Samples of cancer cells suspended in buffer solution with the ratio of dry material to liquid ～1:10 were prepared and measured. The work will serve as the foundation for future work defining specific spectra associated with different tumor histologies and tumor progression and metastasis.
