Membrane protein activity measured by high-speed atomic force microscopy (HS-AFM): A probe (oscillating tip shown in orange) hovering over the single closed ion channel in a membrane (left) descends into the channel (right) when it opens. This results in a detectable signal (change in height) over time similar to ion flow measured in single channel recordings. Image courtesy of Dr. Raghavendar Reddy Sanganna Gari.
Researchers at Weill Cornell Medicine have shown that they can...
