Single living cells were studied in growth medium by atomic force microscopy at a high--down to one image frame per second--imaging rate over time periods of many hours, stably producing hundreds of consecutive scans with a lateral resolution of appr

The atomic force microscope (AFM) is calculated to have quantum limited sensitivity using common optical detection techniques. Under typical ambient operating conditions, the AFM is shown to have an energy resolution better than 10−24 J, considerab

In many prokaryotic cells (eubacteria and archaebacteria) the outermost cell envelope component is composed of a regularly structured protein surface layer (S-layer). The two-dimensional S-layer from Bacillus coagulans E38-66 and Bacillus sphaericus

A low-temperature force microscope has been demonstrated which is suitable for both repulsive and attractive mode (including magnetic) imaging. This instrument uses microfabricated cantilevers and an all-fiber interferometer for remote sensing of can

High‐resolution inelastic neutron scattering was used to investigate the rotational tunneling of methane molecules in a ■×■R45° commensurate, square‐lattice–solid monolayer adsorbed on MgO (100) surfaces. Good matches to the observed tran

The geometry of a nematic liquid crystal (LC), 4-n-octyl-4'-cyanobiphenyl (8CB) on the (0002) surface of graphite is studied by scanning tunneling microscopy. The tilting of cyanobiphenyl-groups on a substrate is observed. Molecular orbital calculati

GRAPHITE is a popular choice as a substrate for the study of absorption of molecules on surfaces because of its relatively simple interaction with adsorbates and the ease of preparing a clean and homogeneous surface. Here we use scanning tunnelling m

Switching behavior between electron tunneling and ballistic transport states was induced by repeatedly bringing a sharpened nickel wire into contact with a gold surface. The high-conductivity ballistic state had a quantized conductance of 0.977 +/- 0

Guanine, one of the four DNA bases, has been observed by tunneling microscopy to form a two-dimensional ordered structure on two crystalline substrates, graphite and MoS2. The two-dimensional lattice formed by guanine is nearly identical on the two s
