LVEM5 installed at McGill University

The Chemistry department of McGill Univeristy has selected the LVEM5 Benchtop electron microscope to add to its research instrumentation.


Dr. Amy Blum's research group focuses on creating novel nanostructured devices and materials through self assembly. They take advantage of the unique properties of nanoscale and nanostructured materials by inventing new techniques for assembly and construction. Creating such materials will likely result in the emergence of previously unseen physical and chemical properties. Understanding and exploiting these properties will enable new and cheaper approaches to designed materials for many purposes such as photonics, electronics, and sensing applications.

 

Using biomolecules such as DNA, proteins, and intact virus particles as scaffolds to take advantage of the specificity and versatility they provide. These biotemplates give us access to a size scale that is difficult or impossible to reach using other techniques, particularly for assembly in three dimensions. Projects will use Tobacco Mosaic Virus and DNA as templates for organizing nanoparticles to generate hybrid materials with a negative index of refraction, molecular electronics-based nanosensors, magnetic nanoparticle-based data storage structures, and plasmonic structures that can act as waveguides or antennas.

The LVEM5 is the only desktop TEM on the market that allows for hands on student use. The LVEM5 is also capable of preforming electron diffraction. The LVEM5 is capable of 1.2nm resolution in TEM mode and 3nm in SEM mode.

The LVEM5 benefits from a 5kv electron source that means that you can visualize light weight materials such as biological tissue without the need for heavy metal stains. This is a huge advantage for users who want to get a greater understanding of their materials, and not their stain.
