Caltech Physicists Create First Nanoscale Mass Spectrometer

The new technique, developed over 10 years of effort by Michael L. Roukes, Professor of Physics, Applied Physics, and Bioengineering at the Caltech and codirector of Caltech's Kavli Nanoscience Institute, and his colleagues, simplifies and miniaturizes the process through the use of very tiny nanoelectromechanical system (NEMS) resonators.
