Observing mammalian cells with superfast soft X-rays - EurekAlert
Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them. Refined Wolter mirrors, a type of ultraprecise mirror, were created to enable the microscope to capture images with high spatial resolution and a wide field of view. In the future, the team hopes to use this microscope to better understand the dynamic nature of cellular biology.
