Biocompatibility of the liquid metal electrodes. (A) DIC image (left) and merged DIC and fluorescent images (right) of neurons labelled with CellTracker AM (green) and propidium iodide (red). Scale bar, 100 μm. (B) Quantification of viability near the interface region (“near”) and away from the electrode (>3 mm away) (“far”). (C) A typical optical recording of spontaneous calcium transients measured from somata within the cell channel containing the liquid metal electrodes. The solid lines = mean.
