Greener synthesis approaches for nanotechnologies have received much attention over the last decade. As the key descriptor of a nanomaterial involves its physical dimensions, at least one of which is on the length scale of nanometers, confirmation of a successful synthesis requires measuring these physical dimensions. Silver nanoparticles in particular have received attention for their use as an antimicrobial agent by releasing silver ions. This talk will focus on how a fundamental understanding of the various metrologies employed to characterize the size of silver nanoparticles can enable more meaningful intercomparison of sizing results across synthesis studies and nanoEHS risk assessment studies.  Additionally, by measuring silver nanoparticles' intrinsic instabilities under relevant conditions and typical storage and handling conditions, fundamental knowledge can be developed to not only intercompare results across green synthesis studies but to also enable better prediction of their fate, transport, and behavior in the environment.
