New Single-Molecule Detector

July 10, 2007

Using tiny silicon rings that trap and circulate light, researchers have made an ultrasensitive device that can detect single biomolecules. Unlike standard techniques for detecting individual molecules, the new method, described online in Science last week, does not require labeling the target molecules with fluorescent tags, potentially making it simpler and less expensive.
