Environmental Health Perspectives featured a study that aimed to examine hazards of well-characterized high production metal oxide nanoparticles (NPs) due to the increasing concern involving occupational exposure via inhalation. A Brookhaven NanoBrook 90Plus Particle Size Analyzer was used to determine the hydrodynamic size of NPs. With it, researchers Wan-Seob Cho and his colleagues were able to evaluate the inflammation potencies of the NPs used. The study was entitled, “Metal Oxide Nanoparticles Induce Unique Inflammatory Footprints in the Lung: Important Implications for Nanoparticle Testing.”
Through this study, the researchers were able to conclude that different types of inflammation imply different hazards in terms of pathology, risks and risk severity. The results of the study showed that NPs could not be viewed as a single hazard entity and that risk assessment of NPs should be performed separately and with caution when used in innovative studies in industry, cosmetics and biomedicine.
Metal oxide nanoparticles are already in use and have potential to be used in various applications for instance in the development of new industrial applications. An advanced technique in nanoparticle characterization allows scientist to have accurate analysis to further understand and differentiate its properties. Brookhaven’s NanoBrook 90Plus Particle Size Analyzer is a fast, effective and compact instrument ideal for nanoparticle characterization.
