Abstract

Cryofixation yields outstanding ultrastructural preservation of cells for electron microscopy, but current methods disrupt live cell imaging. Here we demonstrate a microfluidic approach that enables cryofixation to be performed directly in the light microscope with millisecond time resolution and at atmospheric pressure. This will provide a link between imaging/stimulation of live cells and post-fixation optical, electron, or X-ray microscopy.
