Measuring pressure driven flow in nanotechnology involves several advanced techniques. Some of the most common methods include:
1. Micro-PIV (Particle Image Velocimetry): This technique uses microscopic particles and a camera to visualize and measure flow velocities. 2. Pressure Sensors: Highly sensitive pressure sensors can be placed at various points in a micro- or nanofluidic device to measure the pressure gradient driving the flow. 3. Electroosmotic Flow Measurement: In some cases, the flow can be indirectly measured by analyzing the movement of ions in the fluid.
