The Centre for Ultrastructural Imaging (CUI) is the central electron microscopy facility at King’s College London. We provide a state-of-the-art facility to internal and external collaborators from academic, commercial, and industrial sectors across medicine, biological sciences, chemistry, physics, materials sciences, and engineering.
Our vision is to deliver expert electron microscopy services through a collaborative research environment, offering support in experimental design, advanced imaging techniques, data interpretation, and training.
We provide cutting-edge technology and comprehensive workflows to support electron microscopy imaging in life and materials sciences.

Transmission Electron Microscopy (TEM)
TEM is a powerful imaging and analytical technique, that enables the visualisation of internal structure of materials at atomic resolutions. It allows researchers to analyse composition, morphology, and structure at nanoscale levels.

Scanning Electron Microscopy (SEM)
SEM uses a focused electron beam to scan across the surface of the specimen eliciting the emission of secondary electrons that generate an image showing topographical detail.

Energy Dispersive X-ray Spectroscopy (EDS)
Energy Dispersive x-ray Spectroscopy is used to determine and quantify the elemental composition of a sample.

Serial Block Face Scanning Electron Microscopy (SBF-SEM)
SBF-SEM an automated 3D imaging technique that combines in situ ultramicrotomy with scanning electron microscopy.

Correlative Light and Electron Microscopy (CLEM)
CLEM is an imaging technique that combines fluorescence light microscopy (FM) and electron microscopy (EM) to analyse the same biological sample.

TEM Tomography
Electron tomography is a technique that involves tilting a specimen within an electron microscope to capture images from multiple angles, allowing for the reconstruction of a three-dimensional image.

Scanning Transmission Electron Microscopy (STEM)
STEM is an advanced imaging technique that provides high-resolution images and spectroscopic data by scanning a focused electron beam across a very thin sample and collecting various signals in parallel.
Facility staff
