Examining Materials in Liquids Using Transmission Electron Microscopy

Accurately examining materials in liquids using electron microscopy is a difficult task for scientists, as electron beams perturb the sample and induce artifacts. This is especially true when using in situ liquid transmission electron microscopy (TEM) and scanning TEM (STEM) to probe nanomaterials. Scientists at Pacific Northwest National Laboratory (PNNL) and University of California, Davis demonstrated that in in situ liquid experiments, the choice of electron beam energy has a strong effect that goes far beyond merely increasing the concentration of reducing radicals. They also found that when compared to solid samples, radicals formed in the liquid phase are more mobile, and ultimately dictate the choice of TEM imaging mode.

Angewandte Chemie: Nanocosmos of Cells Under the Magnifying Glass

Angewandte Chemie publication: Picture a satellite orbiting the Earth and capturing numerous individual images of the planet at night in impressive definition, which, when combined to create one single large photograph, deliver an extremely detailed picture of life at night on the surface of the Earth. Only, in this case, the camera is not orbiting the Earth; it is traveling across human cells. And the light captured does not come from street lights, headlights, and lamps, but from specific structures inside the cell membrane or, more accurately, from glycoproteins and lipids illuminated using a special technique.

One-Nanometer Synthetic Molecular Successfully Observed and Touched

A research group led by Professor Hiroyuki Noji, Department of Applied Chemistry, Graduate School of Engineering, University of Tokyo, successfully observed and touched the rotational motion of a 1-nm synthetic molecular machine through the application of a single-molecule capturing and manipulation technique using optical microscopy and a bead probe (single-molecule motion capturing), which allows visualization of molecular mechanical motion. more

Lasers Makes Atomic Force Microscopes Way Cooler

Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive and capable of detecting forces as small as the weight of an individual virus. The technique, developed by researchers at The Australian National University (ANU), hinges on using laser beams to cool a nanowire probe to minus 265 degrees Celsius. more
