Recording from distinct regions of cardiomyocyte monolayers. (A) A patch of beating cells (red dashed oval) over a NWFET (yellow arrow) with sensitivity of 12.8 nS/mV. (Scale bar, 40 μm.) (B) Conductance vs. time signals recorded from the cell patch presented in A. The average signal amplitude is 53.2 ± 4.0 nS. (C) Distinct patch of beating cells (red dashed oval) over a NW device (yellow arrow) with sensitivity of 9.2 nS/mV. (Scale bar, 20 μm.) (D) Conductance vs. time signals recorded from the cells in C. The average signal amplitude is 19.1 ± 3.1 nS.
