By passing electrons through a nanometer-scale grating Researchers at the National Institute of Standards and Technology (NIST) have imparted the resulting electron waves with so much orbital momentum that they maintained a corkscrew shape in free space. This opens the possibility of adapting transmission electron microscopy for quick and inexpensive imaging of a larger set of magnetic and biological materials with atomic-scale resolution.
MIT electrical engineers have proposed A non-invasive electron microscope that would allow researchers to observe molecules inside a living cell without disturbing them. I
Researchers from the University of Antwerp, Centrum Wiskunde & Informatica (CWI) and Switzerland have developed a new method to visualize individual atoms inside tiny particles. They applied sophisticated measuring techniques to advanced electron microscopy images.
NCMIR scientists, in a collaboration with a team led by Nobel laureate Roger Tsien, introduced a new fluorescent probe for correlated light and electron microscopy that overcomes many of the limitations previously encountered by researchers seeking to image cells and tissues at high resolution. This probe, termed “miniSOG” (for mini singlet oxygen generator) was genetically engineered from a portion of the native protein phototropin-2 from the plant Arabidopis thaliana and can be used much like the genetically encodable family of fluorescent proteins obtained from jellyfish that have revolutionized modern light microscopy.
Carl Zeiss Nano Technology Systems, CEOS GmbH, and the University of Ulm have completed 2 years of evaluation and are starting the second phase of the Sub Angstrom Low Voltage Electron Microscope (SALVE) project.
Structural determinations of the of crystals as small ass 100 nanameters are done using single-crystal electron diffraction tomography, a technique developed by Dr. Ute Kolb at Johannes Gutenberg University Mainz.
Abberation corrected electron microscopes incorporate aberration-correcting electron optics to increase resolution
A team of researchers from the Max Planck Institute for Biochemistry (Germany), led by spanish physicist Rubén Fernández-Busnadiego, has managed to obtain 3D images of the vesicles and filaments involved in neuronal communication. The method is based on a novel electron microscopy technique that cools the cells freezes so quickly that biological structures in full swing.
Dr. Hong Zhou of the University of California at Los Angeles (UCLA) and the California NanoSystems Institute (CNSI) has achieved atomic resolution of viruses in solution for the first time ever recorded using a Titan Krios™ transmission electron microscope (TEM).
Together with the University of Ulm and CEOS (Heidelberg), Carl Zeiss SMT has initiated a development partnership for low-voltage transmission electron microscopy.
DTEMs could achieve resolutions 100 times greater than currently attainable for live processes, enabling scientists to observe and record biological processes at the molecular level.
