Two-Terminal Nanoscale Transistor Sensor (image) Harvard University Caption This shows the delivery of a two-terminal nanoscale transistor sensor into single cells. The device has a three-dimensional and flexible structure with the key nanoscale field-effect transistor element synthetically-integrated at the tip of the acute-angle nanowire nanostructure. 3-D nanoprobes modified with phospholipid bilayers enter single cells in a minimally-invasive manner to allow robust recording of intracellular potential.
