Figure 3From: Biomolecular Nano-Flow-Sensor to Measure Near-Surface FlowTime course of the velocity dependency of F1-bead rotation. F1-bead rotations are measured at four different near-surface velocities. The insets show the centroid plot of the bead position at 33 ms intervals. In the experiment, the rotation is halted at more than 22 μm/s (data not shown)Back to article page
