Home Latest News New 100 keV CryoEM detector launching with collaborations from STFC, The Franklin and Quantum Detectors

A new generation of detector, based on technology developed by UK Research and Innovation (UKRI), is set to transform the field of electron cryo-microscopy.

Technology developed by the Science and Technology Facilities Council (STFC) in partnership with the Engineering and Physical Sciences Research Council (EPSRC) funded Rosalind Franklin Institute and MRC Laboratory of Molecular Biology (MRC LMB) is being brought to market by Quantum Detectors. STFC and Quantum Detectors have signed a non-exclusive licence for the detector design.

Electron cryo-microscopy, also known as cryoEM, uses precision high energy beams of electrons rather than visible light to study the structure of biological samples at cryogenic temperatures to achieve imaging at the atomic level.

The innovative detector technology developed by STFC’s Technology department will eventually lead to cryoEM techniques becoming available to non-specialist laboratories while specialist laboratories can undertake more complex work, raising the standards of research across the board.

Until now, the leading industry standard cryoEM systems have all required huge amounts of power. The standard systems operate with 300keV electron sources and are complex, specialised machines that are only available in specialist microscopy centres.

Recently, pioneering scientists demonstrated that similar imaging resolutions could be achieved with electrons at a much lower energy of 100keV.

The new commercial venture with Quantum Detectors aims to provide a detector which can aid in radically simplifying the microscope design. This will ultimately make the technique much more accessible and widely-used across science and industry.

Dr Barbara Ghinelli, STFC’s Director of Campus Development and Clusters and a Rosalind Franklin Board Member, said: “This is an excellent example of how the research base and industry can come together to develop and commercialise world-leading technology that will benefit society.”

STFC’s Technology department developed the technology in consultation with cryoEM pioneer and Nobel Prize winner, Dr Richard Henderson and MRC Laboratory of Molecular Biology (MRC LMB) group leader Dr Chris Russo.

Dr Hazel Housden, the Rosalind Franklin Institute’s Innovation and Translation Manager, said: “This is an exciting step forward in the democratisation of the cryoEM technology. It will make the technique accessible to everyday laboratories, allowing many more researchers to obtain high resolution images of their own biological samples in-house, and free up specialist labs to undertake more complex research and development work. We are looking forward to seeing the great discoveries that will come from this revolution.”

The Quantum C100 detector, based on innovative work at STFC, has been optimised for 100 keV and has been developed as a key component to facilitate economic access of the emerging field of imaging around the world.

Roger Goldsbrough, CEO of Quantum Detectors, said: “We’ve been providing advanced detector solutions for almost 15 years now, and the introduction of the Quantum C100 will take product innovation to another level.  We are absolutely delighted to have been selected to partner with the Rosalind Franklin Institute and the STFC, to help bring CryoEM technology to a far wider scientific community, with a whole new class of instrumentation delivering the higher quality data that scientists need.”
