A research study entitled, “Stability And Aggregation Of Metal Oxide Nanoparticles In Natural Aqueous Matrices” was conducted to present a better understanding of the factors that influence fate and transport of metal oxide (MeO) nanoparticles in a diverse array of real environment media.
In this study, the researchers dispersed MeO nanoparticles, TiO2, ZnO and CeO2 in eight different aqueous media associated with seawater, lagoon, river and groundwater. These nanoparticles were then subjected to a dynamic light scattering technique using Brookhaven’s own BI-200SM to obtain particle size at different stages of the aggregation process. The electrophoretic mobility of the various particles was also measured using Brookhaven’s NanoBrook ZetaPALS. Results from these measurements determined how these nanoparticles traveled in different water media and how it affected factors such as toxicity. Through this study, key information for designing and interpreting nanoparticle ecotoxicity studies in various environmental conditions was gathered.
The increasing use of nanomaterials in consumer products calls for advancements and innovations in its preparation and production. Scientists and researchers use only reliable and precise instruments when handling nanomaterials. Brookhaven Instruments provides reliable, accurate and convenient equipment for particle size analysis, such as the BI-200SM and NanoBrook ZetaPALS.
