Figure 1. Overview of KNW synthetic designs and potential applications.

Figure 1

a, U-shaped KNW with integrated nanoFET (red) shown as a bioprobe for intracellular recording. b, W-shaped KNW with multiple nanoFETs (red) illustrated as a bioprobe for simultaneous intracellular/extracellular recording. In a and b, green indicates heavily-doped (n++) S/D NW nanoelectrode arms, red highlights the pointlike active nanoFET elements, and gold indicates the fabricated metal interconnects to the NW S/D arms. A schematic of a cell to scale is drawn with the different device designs to show the potential for achieving minimally invasive deep penetration (a) and multiplexed intracellular and extracellular recording (b).
