Electron Microscopy

Nanotechnology is an emerging field considered to likely have a major impact on medicine, agriculture and the environment therefore generating substantial economic benefits in the next decade.  Essential requirements are clean rooms for assembly of nanostructures and electron microscopes for imaging the molecular structures, microanalysis of complex materials and nanofabrication of fluidics systems.

The Institute's $10m Electron Microscopy Unit and clean room facility is a key facility designed for physical sciences, life sciences and engineering applications.  The unit is equipped with five state-of-the-art electron microscopes available to academic and industry users on a fee for use basis.

The electron microscopes include: 

 

FEI Quanta Scanning Electron Microscope (ESEM)

Environmental Scanning Electron Microscope fitted with a Peltier cold stage operating from -25 to + 40C. Designed for high resolution imaging of the surface morphology of biological and materials science preparations.

 
FEI Quanta scanning EM

Philips XL-30 Scanning Electron Microscope

SEM equipped with an X-ray microanalysis system for elemental analysis.

 
vimentin intermediate filaments using non-invasive cryo-EM techniques

FEI Nova dual beam, focussed ion beam system

Combined SEM and gallium ion beam instrument. Equipped with EDAX, Pt-deposition system and micromanipulator. Suitable for device cross-sectioning, TEM sample preparation and nanofabrication.

 
FEI Nova dual beam EM

 FEI Tecnai F30 Transmission electron microscope

Equipped with an anti-contaminator and cold stage which allows imaging of quick frozen samples under cryo-electron microscopy conditions. The main application of this microscope is in the structural investigation of biological macromolecules.
