September Winners

Category: SEM

Vascularisation

Courtesy of Mr. Oliver Meckes

This is a freeze-fraction through a metastasis of adenocarcinoma. The tumor has sent out signals to the organisms to build blood vessels which can be seen here. The process is called vascularisation. Blood vessels are coloured yellow, the cancer red, some tumor-infiltrating lymphocytes are shown white, connective tissue is grey. Magnification 1600x when 15cms wide.

The Leukolike

Courtesy of Mr. Michael Evangelopoulos

Leukolike Vectors are carefully engineered using white blood cell membrane to create cellular patches on the surface of porous silicon nanoparticles. This strategy bestows the nanoparticle core with biomimetic properties with the transfer of over 150 proteins onto the particle's surface.

Fly Ash

Courtesy of Mr. Jan Goral

3D visualization of a fly ash (coal combustion product) reconstructed from the Helios NanoLab DualBeam FIB-SEM image dataset using the PerGeos software. Fly ash is studied by scientists from the National Energy and Technology Laboratory (NETL) under the rare-earth elements (REEs) recovery from coal and coal by-products research project (https://www.netl.doe.gov/research/coal/rare-earth-elements).

Tangled up in blue

Courtesy of Prof. David Pérez-Morga

False-colored SEM image of the parasite Trypanosoma brucei gambiense (15-20 µm long, in blue) responsible for human sleeping sickness in Western and Central Africa, here intertwined with red blood cells (5 µm, in red) in a blood capillary (green). At the peak of the infection the parasite density is up to millions of trypanosomes per ml of blood. Studying the difficult relationship between the parasite and the human immune system, lead to our laboratory to engineer therapeutic proteins that kill pathogenic trypanosomes in vivo (see Fontaine et al. Nature Microbiol. 2017; 2:1500-6). Laboratory of Molecular Parasitology and Center for Microscopy and Molecular Imaging, Université Libre de Bruxelles, Belgium (Frédéric Fontaine, Daniel Monteyne, Etienne Pays and David Pérez-Morga).
