A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, CRISPR, and quantum dots to generate a clear signal from just a few molecules. In lung cancer tests, it worked even in real patient serum samples. Researchers hope it could eventually power portable blood tests for cancer and other diseases.

    Cool tech, looks much more versatile than just cancer biomarkers. General reminder that we all get cancers on the regular and our immune systems take care of them, so used unwisely things like this can lead to unnecessary (and profitable) procedures.
