Cylinders of nickel grown by electroforming and after lift-off of the corresponding resist mask. In some cases, the nickel overpassed the resist (muffins), while other cylinders broke at the base (little tarts). The resist has been written with the photolithography technique.

Wireless Utah Neural Electrode array

The image shows a 10*10, 1.5mm long, 400 micron pitch Utah Neural Wireless Electrode array for communicating with individual neurons from the brain. The substrate consists of machined crisscross channels which are 500 μm deep, filled with glass frits (insulator between each electrode), with backside metallization (not visible in the picture) using microfabricaion techniques for integration with the electronics. The frontside of the array is machined into 100 electrodes on a wafer level followed by acid etching of the columns to form pointed needles with fine surface texture. The tips of all the electrodes are coated with Iridium oxide in order to communicate with neurons during the stimulation and recording from the brain.

Sildenafil Crystals

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.

The captions shows the dramatic encounter, in the liver, of our unsung heroes, the immune cells, and an invading parasite, the trypanosome. Each side bears an impressive arsenal of chemical weapons that will define at the end the unset, or not, of the Sleeping Sickness.
