UI Associate Professor Thomas Peters is Principal Investigator on the study “A Nanoparticle Respiratory Dose Sampler for Metal-Based Nanoparticles,” which was recently funded by a more than $1.2 million NIOSH grant. Along with co-PIs Professor Vicki Grassian and Assistant Professor Renee Anthony, Dr. Peters is using this grant to further work on a recently developed novel personal sampler — the nanoparticle respiratory dose (NRD) sampler — and an associated analytical method that is easy to use, is inexpensive to analyze, and integrates into current personal exposure sampling strategies that can streamline the multi-step process for assessing titanium dioxide nanoparticle exposures. The work will expand the applicability of the NRD sampler and associated analytical methods to dramatically improve exposure assessment of a broad range of metal-based nanoparticle exposures in the workplace.
