Summary
Previously, EMBL scientists developed a new microscope based on Brillouin scattering – a phenomenon where light interacts with naturally occurring thermal vibrations within materials, from which their mechanical properties can be deduced. This method has since been used for non-invasive and live-imaging applications in biology, and that advance was selected as one of The Guardian’s 10 biggest science stories of 2022.
In a new paper, the same scientists have now succeeded in substantially further advancing Brillouin microscopy, making it approximately a thousand times faster and more efficient.
