X-ray microscope images cells faster, without the need for dyes

When obtaining three-dimensional images of cells using a scanning electron microscope, individual cells are scanned one section at a time and those images are then put together to form one complete 3D picture of that cell – the process often takes a long time to complete. When using a fluorescence microscope, cells must first by dyed so that they show up against their surroundings. Now, a team from Helmholtz-Zentrum Berlin (HZB) have demonstrated a process called X-ray nanotomography, that can instantly obtain 3D images of cells in their almost natural state.
