Utrecht scientists have succeeded in measuring the mass of individual molecules. By modifying an existing mass spectrometer and developing special software, the researchers succeeded in making ultra-sensitive measurements. This enables them to measure each particle separately in a mixture of molecules for the first time. This has far-reaching applications in, for example, gene therapy products, in which a precise measurement method is crucial. The researchers will publish their findings on 9 March in Nature Methods.
