The Malvern Panalytical NanoSight range of instruments utilizes Nanoparticle Tracking Analysis (NTA) to characterize nanoparticles from 10nm -2000nm* in solution. Each particle is individually but simultaneously analyzed by direct observation and measurement of diffusion events. This particle-by-particle methodology produces high resolution results for particle size distribution and concentration, while visual validation provides users with additional confidence in their data. Both particle size and concentration are measured, while a fluorescence mode provides differentiation of labelled or naturally fluorescing particles.
