Cutting edge high-resolution 3D imaging technology for biological material developed by M Squared in conjunction with research partners.
The first pictures are released from our life science studies with partner researchers using a new light-sheet microscope for use in 3D biological studies.
M Squared has worked with researchers including those at the University of St Andrews, The Maurice Wohl Clinical Neurosciences Institute, Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at Kings College London, the National Physical Laboratory in conjunction with University College London and the Niels Bohr Institute in Copenhagen, applying cutting-edge laser imaging technology and data science capabilities to bypass previous technological obstacles to imaging living cells and tissues.
Our ‘Aurora’ Airy Beam Light-Sheet Microscope has been used by researchers to produce 3D images fine enough to capture neural connections. The research represents a huge step forward for 3D volumetric imaging and is leading to increased understanding of neuro degenerative diseases and organ regeneration.

The Aurora microscope is also able to achieve high-contrast 3D images up to 500 times faster than conventional confocal microscopy techniques and with minimal damage to tissue. New images released by M Squared show the Aurora technology in action. The release of the images follows the Institute of Physics Business Innovation Award, recently awarded to M Squared at the Houses of Parliament, for its work on microscopy.

Aurora is enabling new discoveries in neuroscience research currently being undertaken in the Neurodegeneration Unit at the IoPPN, where scientists are shedding new light on neurodevelopmental and neuropsychiatric disorders including autism spectrum disorders, schizophrenia and intellectual disability.

The ability to accurately image large biological structures at a cellular level is fundamental to modern biological understanding. In recent years there has been difficulty in creating images of larger neural structures in the detail necessary to understand how they interact at sub-micron level.
Changes to the brain that take place throughout one’s life – known as structural plasticity – are thought to govern neural circuit refinement and information storage. Certain chemicals in the brain can dramatically influence these changes, but much less is known about the molecular mechanisms by which these chemicals control these changes.
Research into these reactions could trigger further breakthroughs in understanding neurodegenerative disorders including dementia, Motor Neuron Disease and Parkinson’s Disease.
Dr Deepak Srivastava, Institute of Psychiatry, Psychology and Neuroscience at King’s College London and Director of the Wohl Cellular Imaging Centre commented:
The Wohl Cellular Imaging Centre (WCIC) provides advanced and cutting-edge light microscopy solutions for neuroscientists and related life sciences with the aim of helping to advance breakthrough discoveries in the development and treatment of life-changing illnesses. As such, the effectiveness of the facility is heavily reliant on the cutting-edge and innovative nature of the microscopes in the centre. Aurora has already allowed researchers to gain unprecedented insight into key scientific questions.

Alongside neuroscience research, M Squared’s Airy Light-Sheet technology is also being used in research on neural organoids, stem cells, and how the pancreas develops in Zebrafish.

The Airy Light Sheet Microscope has a uniquely large field of view meaning that larger neural structures can be viewed with high resolution. The Airy Light Sheet Microscope has a 600 micron field of view, 20 times larger than a standard Gaussian light sheet. This method of imaging has very low phototoxicity and photobleaching, so the specimen can be imaged for longer.

Earlier this year, M Squared was granted a Prosperity Partnerships fund with the University of St Andrews for their joint work in the diagnosis and treatment of dementia and cancer. Funding for this research comes from a new £78 million government fund from the Engineering and Physical Sciences Research Council (EPSRC) and the Industrial Strategy Challenge Fund (ISCF).
M Squared opened its specialised biophotonics division ‘M Squared Life’ at the Surrey Research Park in 2015. Since its formation, M Squared has worked closely with Kishan Dholakia’s group at the University of St Andrews to develop a portfolio of IP. The Aurora airy-beam light sheet microscope is the first transformative imaging technology that the company has commercialised.
