Movie S3. Time-lapse movie of nanowire growth by S. oneidensis MR-1 in the perfusion platform. Green fluorescence is the result of protein staining by NanoOrange. The nanowires grew in the direction of perfusion flow (5 µL/s). In this movie, a cell produced two nanowires, one is 6 µm and the other is 13 µm long. The interval between two consecutive frames is 5 min, but is reduced to 200 ms in the movie. (Scale bar: 5 µm.)
