Since the 1950s, scientists have worked around this problem by coating samples with a thin layer of gold before imaging. While this approach made electron microscopy possible for countless discoveries ...

A light-powered microscope has a resolution limit of around 200 nanometers—which makes observing specimens smaller or closer together than that all but impossible. Engineers at the University of ...

Most conventional light microscopes have a resolution of 200 nanometers – this means that imaged objects which are any closer to one another won't be seen as separate items. A new high-tech microscope ...
