Physorg.com -- This is a to scale schematic of a kinked-nanowire electronic sensor probing the intracellular region of a cell. The two-terminal device has a three-dimensional and flexible structure with the key nanoscale 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.
