Cancer Genes Detected with Liquid Lasers

Facebook X LinkedIn Email
ANN ARBOR, Mich., Feb. 1, 2012 — Genes linked to cancer and other diseases may now be easier to detect with a new method that uses liquid lasers to distinguish mutated DNA from healthy DNA by a single base. Researchers at the University of Michigan say their technique works better than the current approach, which uses fluorescent dye and other biological molecules to find and bind to mutated DNA strands. When a patrol molecule catches one of the mutated genes, it emits a fluorescent beacon. Although it sounds effective, the patrol molecules tend to bind to healthy DNA as well, giving off a background glow that is only...Read full article
