Nanoparticle Analysis - Imaging of Nanoparticles Moving in Brownian Motion

The video clip shows 100+200nm polystyrene particles moving under Brownian motion as seen by the NanoSight LM20. The technique looks at the rate of Brownian motion and relates the speed of movement, to particle size. As the technique produces particle size on a particle by particle basis, distinct particle populations can be discriminated even when the particles are closely matched in terms of particle size. The ability to individually size nanoparticles overcomes the innate problems associated with other techniques which produce intensity weighted, average particle sizes.
