The Scanning Electron Microscope (SEM) image is of ‘Nano Swimmers’ that are currently being investigated for potential use as novel drug carriers. These coiled structures are 25 microns in length, 5 microns in diameter and 300 nanometres in thickness. They are composed of a polymer with nickel/titanium coating and were fabricated by the Multi-Scale Robotics Laboratory, ETH Zurich and in collaboration with the NanoMedicine Laboratory, UCL School of Pharmacy. The swimmers were imaged under a FEI Quanta 200F Scanning Electron Microscope; firstly, the sample was given a 5nm gold coating in a Quorum Q150 Sputter coater and imaged at 5KV. In addition a tilt angle of 65 degrees enhanced their full structure, high resolution digital images were captured and imported into photoshop, where they were artistically manipulated and coloured by Ms Annie Cavanagh.

This image is of salmonella bacteria, a low kV was essential in order to visualise the surface detail of the bacteria, so the image was taken with the VcD (backscatter detector), using beam decelleration.

Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless. In lightweight plaster and concrete, vermiculite provides good thermal insulation. Vermiculite can absorb such liquids as fertilizers, herbicides, and insecticides, which can then be transported as free-flowing solids.

Sildenafil is the active ingredient in Viagra tablets.Sildenafil was re crystallised in 10% alcohol and allowed to air dry, then adhered onto a SEM stub using double sided carbon adhesive discs, prior to viewing the sample was gold coated in an Emitech K550 Sputter Coater for 2 minutes at 20mA. The coated sample was then transferred into a FEI XL30 Scanning Electron Microscope and imaged at 10KV using a high tilt angle. High definition digital images were captured and imported into Photoshop for enhancing and colouring.

Immune surveillance by macrophages and monocytes is important for removing foreign invaders from the body, eliminating dead or damaged cells, and tissue homeostasis. Functional plasticity of macrophages enables them to respond to different stimuli, performing a variety of immune modulatory roles. During tumor development, macrophages are among the first immune cells to migrate into the tumor. Stimuli, including molecules secreted by cancer cells, polarize macrophages into various tumor-associated macrophage subpopulations. Factors secreted by macrophages include immunosuppressive cytokines, inflammatory chemokines, and phagocytosis molecules. Shown here are multiple macrophages (white) associating with a breast cancer cell (red). At the University of New Mexico, we are using nanotechnology to deliver agents that influence immune cells to actively participate in destroying tumor cells.

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.
