A nanoelectromechanical systems mass spectrometer (NEMS MS) is an instrument measuring the mass of analyte particles by detecting the frequency shift caused by the adsorption of the particles on a NEMS resonator.

It was first reported by a group of scientists led by Michael Roukes at the California Institute of Technology in 2004.[1] They developed single molecule analysis in 2009.[2] [3] Single-biomolecule mass measurements were accomplished in 2012.[4] A hybrid NEMS-MS/TOF-MS instrument was reported in 2015.[5]
