Mass detection enters attogram regime

Abstract:
Physicists in the US have weighed objects with a mass of just 10-18 grams (attograms) for the first time. Harold Craighead and colleagues at Cornell University made their measurements on small gold dots using a nanoelectromechanical device. The new sensitivity far exceeds the best previous result, which was on the femtogram (10-15 grams) scale. The team hopes their device will be able to detect and identify tiny chemical and biological species, such as viruses. (more on earlier article)
