A human-induced pluripotent stem cell (hiPSC) neuron on a nanowire array. The measured potentials on the right with the small pre-spike oscillations demonstrate the sensitivity of the Nano Assay to minute potential changes in the hiPSC neuron. These small potential changes correlate with the health state of the neuron cell.
