A new device can measure masses as small as one millionth of a trillionth of a gram, in solution. MIT engineers have devised a way to measure the mass of particles with a resolution better than an ...

Researchers have used spectroscopy for label-free chemical and structural imaging of proteins with nanoscale spatial resolution and with sensitivity to single protein complexes of less than one ...

The nanoelectromechanical device used by Craighead and colleagues consists of an oscillating cantilever made from a small wafer of silicon 4 microns long and 500 nanometres wide. When a small particle ...

Nano-scale devices can measure masses with a precision of one attogram, which is three orders of magnitude better than the previous record We tend to associate mass with the quantity or size of an ...

(Nanowerk News) MIT engineers have devised a way to measure the mass of particles with a resolution better than an attogram — one millionth of a trillionth of a gram. Weighing these tiny particles, ...

MIT engineers have devised a way to measure the mass of particles with a resolution better than an attogram — one millionth of a trillionth of a gram. Weighing these tiny particles, including both ...
