Easy Mass Measurement Of Viruses And Nanoparticles
A fast, simple way to find the mass of viruses and nanoparticles has been developed by researchers in Taiwan (Anal. Chem., DOI: 10.1021/ac300615v). The mass distributions of viruses and nanoparticles—which range between 1 megadalton and 1 gigadalton—are hard to measure. Most viruses and nanoparticles have 50 charges or fewer when ionized. This range lies in a detection black hole: Mass spectrometry can easily cope with small molecules . . .
