Infrared holography could provide faster, more accurate cancer diagnosis

Diagnosing cancer from a biopsy currently takes between two days and two weeks. A PhD research project underway at CEA-Leti could help make analyzing biopsies faster and more accurate. The non-operator-dependent method would utilize infrared holography, taking advantage of the specific absorption wavelengths of the DNA, proteins, amides, and other biochemical molecules characteristic of biological tissue samples.

Instead of the current methods, which depend on electromagnetic absorption by water, the approach proposed here would enable in vivo testing. The research is ongoing, and should confirm the potential of this method to identify cancerous tissue in a variety of biopsy samples. One final advantage: It does not require sample preparation.
