The Scanning Electron Microscope (SEM) image is of the head of an embryonic Zebrafish. This is a model organism currently being used for studies into the genetic causes of neurodegeneration. This research project involves Kim Wager, a Ph.D. student jointly supervised by Dr Claire Russell (RVC) and Professor Robert Harvey (UCL School of Pharmacy). The Zebrafish was imaged under a FEI Quanta 200F Scanning Electron Microscope. Firstly, the sample was chemically fixed in 4% (w/v) paraformaldehyde in 0.1M Sodium Cacodylate buffer, followed by dehydration in graduated alcohol and drying in a Leica Critical Point (CPD300) dryer. Prior to imaging, the specimen was given a 5nm gold coating in a Quorum Q150 Sputter coater and imaged at 5KV. In addition, a high tilt angle of 65 degrees enhanced the full structure of the head region. A high-resolution digital image was captured, imported into Photoshop and was artistically coloured by Ms Annie Cavanagh.

Self Assembly of Polystyrene Nanospheres

Self assembly of 500 nm polystyrene nanospheres onto optical photoresist. The nanospheres acts like microlenses, exposing the resist and patterning it with a dot structure. After metalisation (in this case sputtered permalloy) the following lift-off leaves the metal structure on the upper pert of the microphoto. In the lower part the original array of self-assembled nanospheres used as microlenses.

Hybrid inorganic/polymer based photovoltaic nanodevices offer the promise of low cost large area conversion of solar energy to electricity. Nanostructures of zinc oxide have shown supreme capabilities in emerging technologies ranging from solar energy harvesting to biosensing. However, the ability to control the size and position of these nanostructures is crucial for fabricating nanodevices with remarkable properties and astonishing solar energy conversion efficiencies. Herein, we present a collection of scanning electron micrographs of zinc oxide nanostructures prepared by low temperature hydrothermal methods Image taken and Processed by Luisa Whittaker PhD.

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.
