FIGURE 8 Auto-mobile chips: car and wedge. (A) Time-lapse composite of a car-shaped piece of PDMS coated with bacterial carpet. Superimposed images were taken at 5 s intervals from right to left. The arrow marks the first image and direction of motion. (B) Rotation of a triangular piece of PDMS coated with bacterial carpet. The wedge rotates clockwise about one corner, which moves slightly as it drags on the surface below. These images were taken at 2 s intervals. The distance scale is the same as in A. (C) The bacterial carpet of A, containing a mixture of bacteria with long axes perpendicular to the surface (bright circles) or parallel to the surface (fainter oblongs). This carpet is on the upper surface of the PDMS chip (away from the bottom of the assay chamber).
