New Fingerprint Mass Spectrometry Method Paves the Way to Solving the Proteome

Caption

In Caltech's new fingerprint technique, a single molecule adsorbs onto the phononic crystal resonator device. Then scientists measure the frequency shifts of four different vibrational modes of the device, allowing them to create a four-dimensional fingerprint vector—a unique identifier that can then be used to determine the mass of the molecule.
