Photonic sensor for the measurement of sedimentation velocity of particles in complex fluids

Traditional sedimentation measurement methods are often cumbersome and lack precision. The large sample sizes required limit their applicability in industries needing accurate and rapid analyses.

This innovative technology relies on resonant micro-rings to measure sedimentation rates. It provides a dynamic optical signature of sedimentation processes in samples. This method allows for precise measurements of concentrations ranging from 0.1 mg/mL to 10 mg/mL, on tiny samples (droplets or micro-pools). Due to its low-cost microfabrication, it offers a practical and economical solution for sedimentation analysis.
