Nanoparticle Tracking Analysis (NTA) is a particle characterization technique that has grown rapidly since its introduction to the market ten years ago. The current NanoSight instruments have become a critical tool used in many applications to provide information not available by other methods. The ability to visualize individual particles for analysis provides single-particle resolution as well as a direct measure of concentration. The technique also works under fluorescence, allowing speciation of labeled populations in complex backgrounds.
This webinar will review the basic principles of the technique itself, compare it to other established techniques like Dynamic Light Scattering, and provide some example application data sets to show how the information is used in practice.
