Abstract
Gold nanoparticles (AuNPs) are widely used in industrial and medical applications, including chemical catalysts in automotive, surface coatings,
biological imaging, and for diagnosis of cancers and infectious agents. Gold nanoparticles are known to form naturally during the weathering of Au-bearing mineral deposits, as well as the transformation of gold nuggets and particles. In freshwater systems, AuNPs bioaccumulate in aquatic organisms, as shown on test fish species, such as zebrafish and guppy.
Several techniques are available to determine gold concentrations in samples; however, few methods have been developed to characterize the size fractions of nanoparticulate gold in complex organic materials. This work is a feasibility study to measure AuNPs
in complex organic matrices using single particle inductively coupled plasma mass
spectrometry (SP-ICP-MS), as may be applied to environmental monitoring or exploration.
