Figure 4From: Biomolecular Nano-Flow-Sensor to Measure Near-Surface FlowTag-bead size dependence of F1-bead rotation. The size dependence of F1-bead rotation was measured without flow and with flow (0.38 μm/s) by varying the size of the tag-bead from 350 to 800 nm. In both cases, the rotation of F1-bead is linearly proportional to the tag-bead sizeBack to article page
