Novel ultrafast laser detects cancer at earliest possible stage

March 22, 2005 • LOS ANGELES, Calif. — To investigate tumors, pathologists currently rely on labor-intensive microscopic examination, using century-old cell-staining methods that can take days to complete and may give false readings.

Categories: Science / Technology / Engineering

Proof positive — The difference between a normal and cancerous liver cell is shown clearly by the location of mitochondria, as revealed by Sandia's biocavity laser. The healthy cell shows very few mitochondria near the outer cell wall; they cluster densely (red coloration) as they approach the cell's nucleous (depicted here as the black central hole). In the cancerous cell, the mitochondria are spread throughout the cell, do not cluster, and under the same lighting produce a more subdued effect.
