Fig. 2: Assembly of the S collector on an SW cell.
From: Single cell electron collectors for highly efficient wiring-up electronic abiotic/biotic interfaces
a Schematic illustration of S collector assembly. SEM images of b a native SW cell and c an SW@S cell. TEM images of d a sliced native SW cell and e a sliced SW@S cell. PDA, polydopamine nanoparticle; OM: outer membrane of the SW cell. f Fluorescence microscopy image of SW@S cells stained with the LIVE/DEAD assay kit. Green fluorescence indicates living cells; red fluorescence indicates dead cells. Scale bars: b, c 200 nm; d, e 100 nm; f 20 μm; inset of f 2 μm. The inset of f shows an enlarged view of stained cells.
