| Summary: | Obtaining the characteristics of the dispersions of synthesized nanoparticles such as concentration and particle size is an important task in the nanotechnology and biomedicine industries and in many other fields. A rapidly developing method for such needs is nanoparticle tracking analysis (NTA). This technique enables the visualization and recording of nanoparticles sized from dozens of nanometers to a couple of micrometers moving under the Brownian motion. The key point of obtaining precise information about a nanodispersion is video processing, which allows for the quick analysis of the sample without damaging it. Samples of polystyrene and gold nanoparticles with different characteristics were dispersed in water and studied using the NTA device. Dynamic light scattering and transmission electron microscopy were used as the reference methods for nanoparticle characterization. This study also represents the main advantages and drawbacks of using the NTA method in the study of nanoparticle samples of various concentration levels. |
