Development of a direct point electron beam exposure system to investigate the biological functions of subcellular domains in a living biological cell

Micron, The International Research and Review Journal for Microscopy, has published a paper by Tanaka et Al, which reports “the development of a direct point electron beam irradiation system to investigate the biological functions of subcellular domains in a living cell”

Silson’s 50nm silicon nitride membranes separated the atmospheric and the high vacuum environment for the direct point electron beam (DPEB) irradiation; “the focused electron beam penetrated the membrane and formed a nano electron spot whose radius can be down to only a few tens of nanometer at the surface”

The abstract concludes: “Point electron beam exposure is expected to be employed for various cellular stimulation protocols, and this enables the investigation of the biological functions of subcellular domains”
