Web2.5.2 Cryo-Electron Microscopy. Cryo-electron microscopy (Cryo-EM) is a kind of TEM where the sample is examined at cryogenic temperatures (generally lower than –160°C). A feature of cryo-EM is the ability to freeze the specimen rapidly so that water molecules in the specimen turn into transparent ice crystals.

See more WebIt was James Dubochet who put the ‘cryo’ into cryo-EM. He developed a method for freezing water-based TEM samples so rapidly that the water forms a disordered glass, rather than crystalline ice. This is important because ordered ice crystals would strongly diffract the microscope’s electron beam, obscuring any information about the ... personal injury attorneys portland oregon
