NanoSight size analyzer
NanoSight™ size analyzer is a specialized instrument for measuring the size distribution and particle concentration of nanoparticles in liquid suspensions using Nanoparticle Tracking Analysis (NTA). It determines particle size by directly visualizing and tracking the Brownian motion of individual particles, providing number‑based size distributions and concentration measurements. The system is widely used for characterization of extracellular vesicles, viruses, liposomes, drug nanoparticles and other nanomaterials in biological, pharmaceutical and materials research.
