Trabecular Rete of Human Oculus

The trabecular rete of human oculus consists of crossing collagen fibers with cells and extracellular matrix on the surface. Also on the surface of the trabeculae we can see round granules (not bacteria) of organic origin. The use of SEM in ophthalmologic microsurgery allows to evaluate the quality of surgical technique. These studies were conducted jointly with Lyubimova T.S. from Scientific Technical Complex “Microsurgery of oculus”.

Bacteriophage T4 Virus

False-coloured image of T4 bacteriophage incubated with a de novo-designed self assembling peptide fibre (SAF). Small peptides, 28 amino acids long, self assemble to form fibres ~80 nm wide and ~40 microns long. The T4 tail striation distance was being used as a high-resolution calibrant to register the lateral striations of the fibre.

Phoretic Nano-swimmers

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.

Accidental Bacteria

A small colony of bacteria was found proliferating on the surface of a newly developed bio-polymer. While the presence of bacteria was unintentional, the bacterial growth provides evidence for the bio-compatibility properties of the polymer.

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.
