Weighing particles at the attogram scale

January 22, 2014

New device from MIT can measure masses as small as one millionth of a trillionth of a gram, in solution.


The illustration shows a suspended nanochannel resonator (SNR), which can directly measure the mass of individual nanoparticles with single-attogram precision. The inset shows a depiction from inside the embedded fluidic channel, while a DNA-origami gold nanoparticle assembly is passing through the resonator. Image courtesy of Selim Olcum and Nate Cermak.
