Inner Quartz Plasma Tube

Particles were found on the wafer surfaces inline after a plasma was generated through this quartz tube. I cracked open the tube and found how the plasma was etching into the quartz, revealing these structures that would eventually thin enough to break off and land on the wafer.

kidney(glomerular basement membrane)

The glomerular basement membrane (GBM) of the kidney is the basal lamina layer of the glomerulus. The glomerular capillary endothelial cells, the GBM and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule. The GBM is a fusion of the endothelial cell and podocyte basal laminas.

African trypanosome

False-colored SEM image of the parasite Trypanosoma brucei gambiense (15 micrometers long) responsible for human sleeping sickness in Western and Central Africa. Human innate immunity is overpowered by this parasite through a mechanism that we have discovered in our laboratory. We have dedicated the past two decades to study the molecular arms race between humans and trypanosomes and discovered the importance of resistance to these parasites in human evolution.

Silver Clusters - Invisible Worlds

Silver clusters deposited by thermal evaporation onto self-assembled polystyrene nano-spheres (900 nm). Inspect F SEM FEG @ Nanofacility Piemonte INRIM. Self-assembled polystyrene nanospheres are used as masks for thin films and materials nanostructuration on large area. Maybe the subject doesn't match the topics of this year, but surely the title fits.

Cells in a basket

The iSP cells were grown on Matrigel ® by Dr. Koei Chin (OHSU). These cells present tumorigenic phenotype by expressing constitutively active form of Her2 oncogene. They were provided by Dr. William Muller (McGill University, Montreal, Quebec). The SEM image was recorded on a FEI Helios 660 Nanolab™ using BSE mode (Magnification: 8000x). Each cell in the image shows a variety of protrusions: lamellipodia and filopodia.
