  • Description:
    Objective: The generation of nanoparticles is a necessary component for determining health outcomes as they relate to exposure in animal models. Unfortunately, a bulk nanopowder cannot simply be aerosolized into nano-sized particles due to the agglomeration that nanoparticles undergo. The objectives of this research are two-fold; to generate and characterize three different kinds of nanoparticles including one from a bulk source. Methods: This research attempts to generate nanoparticles using three different methods, namely, from a sodium chloride solution, a metal salt solution, and from a bulk nanopowder source. Test aerosols are characterized using three particle counters. Samples are concurrently collected for visual inspection using electron microscopy. Comparative data analysis of the three particle counters relative to visual inspection is performed. Results: Since this research is a work in progress, only limited data has been generated. Preliminary results indicate that NaCl particles can be generated at a predetermined size. One trial produced an aerosol with a dominate particle size of 20 nm. A second trial produced an aerosol with a dominate particle size of 100 nm. Visual inspection of the aerosol has yet to be performed. Conclusion: The generation of particles from salt solutions is not new or novel. For the purpose of this research, it is a necessary aspect as a demonstration of our ability to characterize an aerosol. However, the generation of a nano-aerosol from a bulk nano-powder would be significant. If this method proves successful, it could offer a means to do research on the exposure, dose, and effect of nanoparticles in an animal model. [Description provided by NIOSH]
