Carbon Nanotube Scale Can Weigh a Single Proton

A group of scientists at the Catalan Institute of Nanotechnology in Barcelona, Spain have succeeded in creating a scale so sensitive that it can measure accurately to the smallest unit of mass – the yoctogram. A yoctogram is one-septillionth of a gram, and a proton weighs about 1.7 yoctograms, meaning the scale is sensitive enough to measure a single proton. …
