The atomic force microscope (AFM) is capable of imaging electrically conductive and non-conductive surfaces at atomic resolution. When used to image biological samples, however, lateral resolution is often limited to nanometer levels, due primarily to AFM tip/sample interactions. Several approaches to immobilize and stabilize soft or flexible molecules for AFM have been examined, notably, tethering coating, and freezing. Although each approach has its advantages and disadvantages, rapid freezing techniques have the special advantage of avoiding chemical perturbation, and minimizing physical disruption of the sample. Scanning with an AFM at cryogenic temperatures has the potential to image frozen biomolecules at high resolution. We have constructed a force microscope capable of operating immersed in liquid n-pentane and have tested its performance at room temperature with carbon and metal-coated samples, and at 143° K with uncoated ferritin and purple membrane (PM).

Abstract SSC Invar 36 was developed for use in applications where dimensional stability is essential. It is a nickel-iron alloy with a very low coefficient of thermal expansion from cryogenic temperatures to 200 deg C (390 deg F). It is utilized in aerospace composite tooling and die applications, as well as laser components, and cryogenic components and piping: liquefied natural gas production, storage, and transportation. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming. Filing Code: Fe-158. Producer or source: Sandmeyer Steel Company. Originally published December 2011, revised February 2012.
