Cryo-fracture TEM: direct imaging of a random mesh phase.

Bulut, Sanja LU ; Gonzalez Perez, Alfredo LU and Olsson, Ulf LU (2008) In Langmuir 24(1). p.22-25
Abstract
A novel and a simple method that allows direct imaging of viscous samples by cryo-TEM (cryo-transmission electron microscopy) is presented. A fracture on the vitrified sample is created in a controlled way. In the fracture, some edges are thin enough to allow direct imaging in transmission mode. The method was used to directly image a nonionic surfactant lamellar phase where a random mesh structure is formed at lower temperatures (<10 degrees C). A so-called random mesh phase, characterized by the presence of perforated surfactant bilayers, is imaged here for the first time. Images from the mesh structure are compared with images from the classical lamellar structure formed at room temperature.
