Researchers from the University of South Carolina Arnold School of Public Health’s environmental health sciences department and the South Carolina SmartState Center for Environmental Nanoscience and Risk at the University of South Carolina have collaborated with a scientist from the National Center for Earth and Environmental Nanotechnology Infrastructure to study the synthesis, characterization, and environmental behaviors of platinum nanoparticles. The resulting paper was published in the Journal of Colloid and Interface Science.
The release of platinum group elements, including platinum nanoparticles, has been increasing over recent decades. However, few studies have investigated the fate, behavior and effects of these nanoparticles in environmental media.
With this study, the researchers report a protocol for the synthesis of five different sizes (8.5 ± 1.2, 10.3 ± 1.3, 20.0 ± 4.8, 40.5 ± 4.1, and 70.8 ± 4.2 nm) of monodispersed citrate- and polyvinylpyrrolidone (PVP)-coated PtNPs, together with a characterization of their behaviors in relevant biological and toxicological media.Friday Letter Submission
