Nanoparticle Tracking Analysis (NTA)

Technique de suivi des nanoparticules (NTA)Nanoparticle Tracking Analysis (NTA) utilizes the properties of both light scattering and Brownian motion in order to obtain the particle size distribution of samples in liquid suspension. A laser beam is passed through the sample chamber and the particles in suspension in the path of the beam scatter light in such a manner that they can be easily visualized via a standard light microscope at 20x magnification equipped with a CCD camera. The camera captures a video file of the particles moving under Brownian motion. The NTA software tracks many particles individually and using the Stokes Einstein equation calculates their hydrodynamic diameters. The range provides real time monitoring of the subtle changes in the characteristics of particle populations with all of these analyses confirmed by visual validation.
