Figure 4. Multiplexed ANTT probes.

Figure 4

(A) Design and SEM image of a probe with two independent ANTT devices sharing a common source contact. Horizontal scale bar, 5 μm. (B) Intracellular recording from a single cardiomyocyte using a probe with two independent ANTT devices. The interval between tick marks corresponds to 1 s. (C) SEM image of part of an ANTT probe array fabricated from contact printed Ge/Si NWs. Scale bar, 2 μm. Inset, lower magnification SEM image of the 4 × 4 probe array. Scale bar, 100 μm. Probe interval is about 80 μm. (D) Schematic of chip-based vertical ANTT probe arrays fabricated using epitaxial Ge/Si NWs for enhanced integration.
