Dubbed \u201cattomicroscopy,\u201d the technique can capture the zippy motion of electrons inside a molecule with much greater precision than previously possible, physicist Mohammed Hassan and colleagues report in <em>Science Advances<\/em>.<\/p>\n<p>The attomicroscope is a modified transmission electron microscope, which uses a beam of electrons to image things as small as a few nanometers across. Like light, electrons can be thought of as waves. These wavelengths, though, are much smaller than those of light. That means an electron beam has a higher resolution than a conventional laser and can detect smaller things, like atoms or clouds of other electrons.<\/p>\n<p>To get their superfast images, Hassan and colleagues used a laser to chop the electron beam into ultrashort pulses. Like the shutter on a camera, those pulses allowed them to capture a new image of the electrons in a sheet of graphene every 625 attoseconds \u2014 roughly a thousand times as fast as existing techniques.<\/p>\n<p>The microscope can\u2019t capture images of a single electron yet \u2014 that would require extremely high spatial resolution. But by stringing the collected images together, scientists created a kind of stop-motion movie that shows how a collection of electrons move through a molecule.<\/p>\n<p>The technique could let researchers watch how a chemical reaction occurs or probe how electrons move through DNA, Hassan says. That information could help scientists craft new materials or personalized medicines.<\/p>\n<p>\u201cWith this new tool, we\u2019re trying to build a bridge between what scientists can find in the lab and real-life applications that could have an impact on our daily lives,\u201d he says.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Image &#8211; <em>A new type of microscope used a laser and an electron beam to snap images of electrons moving within a sheet of graphene (illustrated) at a record pace of one every 625 attoseconds.
