Life under the magnifying glass

A smart combination of an optical and a electron microscope can follow individual molecules in their course through a living cell. Named Delmic, the combination microscope is an optical microscope in the vacuum chamber of an electron microscope. Both microscopes view the same object – one from above, and one from below. In her dissertation,
researcher Dr Nalan Liv demonstrates how the optical microscope follows a molecule labelled with quantum dots on its way through a cell. At the same time, she uses the electron microscope to take snapshots of the organelles encountered by the molecule. In this way, the Delmic reveals elementary life processes.
