Researchers have discovered a curious difference between the DNA from cancer cells and that from healthy cells, and this finding could lead to a new blood test for cancer.The difference? Cancer DNA has a rather strong affinity for gold, according to a new study. This feature appears to be common to cancer DNA in general, regardless of the type of cancer, the researchers said.
Taking advantage of this finding, the researchers designed a new test that uses gold nanoparticles to detect cancer. The gold particles change color depending on whether or not cancer DNA is present. The result was a simple and fast test that could detect cancer in just 10 minutes, according to the study, published today (Dec. 4) in the journal Nature Communications.
