Responsibility

Electron Microscopy

• Since completing his PhD in Tissue Engineering, Ashley has specialised in electron microscopy and since working at Brunel University he has become a multi-disciplinary electron microscopist.
• Below are some examples of the work Ashely has carried out using electron microscopical analyses.

• Nano-metre scale SEM imaging using Zeiss Supra 35VP FEG-SEM

• TEM imaging and electron diffraction analysis using Jeol-2100F FEG-(S)TEM

• FIB lift using Zeiss Crossbeam 340 FIB-FEG-SEM

• EDX mapping using Leo 1455VP tungsten filament SEM
