Volatolomics analysis using FTIR spectroscopy for breast cancer identification in vitro

Volatolomic´s analysis is the technique to analysis the volatile organic compounds (VOCs) from the metabolites. VOCs are released by cancerous cells can be one of the bio-diagnostics techniques to diagnose the cancer. FTIR spectroscopy with White gas cell absorption techniques can analyse and detect the key species from VOCs released. Small amount of VOCs samples can be detected by vacuuming the White gas cell and a low concentration gas also can be detected by employing a long effective optical path-length gas chamber. In this preliminary study, methanol was detected from the VOCs released by breast cancer cells.
