Fig. 4: Conductivity measurements of the GY32 cell envelope and nanowire-like appendages by microelectrodes.
From: Long-distance electron transfer in a filamentous Gram-positive bacterium
a Schematic of the single-cell measurement; b single cell on an electrode array observed under a light microscope; c current–voltage curve of a single GY32 cell (n = 5, each from independent bacterial culture); d schematic of the appendage measurement; e appendage network on an electrode array observed by AFM, the dark line indicates a 100 nm height difference between the gap and electrode; f current–time curve of the hydrated appendage products (the voltage is 0.1 V, n = 8 independent bacterial cultures). Plots show mean and standard deviation. Source data are provided as a Source Data file.
