Abstract

Due to their extremely small size, nanoparticles cannot be analyses by conventional approaches such as light microscopy. To visualise particles in the nanoscale range, a combination of an ultra-microscope and a laser illumination unit has to be applied. This combinatory technique is called Nanoparticle Tracking Anlysis (NTA) and can be used of thr nalysis of particles in a size range of approximately 10 nm up to 1 μm in liquid suspension.
