The detection, quantitation, and characterization of nanoparticles using inductively coupled plasma–mass spectrometry (ICP-MS), and in particular using single-particle ICP-MS (SP-ICP-MS), has developed significantly in recent years. However, the difficulties involved in this type of analysis vary, depending on the composition of the nanoparticles. Martín Resano of the University of Zaragoza, together with colleagues from Ghent University, has recently developed a method for characterizing nanoparticles made from silicon dioxide (Si02), which are much more challenging to detect than those made from silver or gold. He recently spoke to us about this work.

Geochronology is an exciting area of atomic spectroscopy and earth science research. One of the goals is to answer tectonic questions, and in particular, how the crust responds to continent–continent collision. John M. Cottle, a professor of earth science at the University of California, Santa Barbara, is one of the scientists on that mission. Cottle and his research group are at the forefront of discovery in geochronology, combining both laboratory and field-based research. In particular, Cottle is a leader in the development of novel laser-ablation inductively coupled plasma–mass spectrometry (LA-ICP-MS) measurements and their application to tectonic questions in convergent orogens, which are mountain ranges formed when a continental plate crumples and is pushed upwards.

There is growing concern about the unknown effects that nanoparticles may have on the environment, especially in drinking water and plants. Single-particle inductively coupled plasma–mass spectrometry (SP-ICP-MS) is emerging as a useful technique for analyzing nanoparticles and their presence in environmental and biological systems. Honglan Shi, a chemistry professor at Missouri University of Science and Technology, and her research group have been using SP-ICP-MS to investigate nanoparticles in drinking water and plant uptake. She recently spoke to Spectroscopy about this work.

The single-particle analytical technique can quantitate the difference between ionic and particulate signals, measure the particle concentration (particles per milliliter), and determine the particle size, size distribution, particle agglomeration, and dissolution. As a result, ICP-MS is a key analytical technique in assessing the fate, behavior, and distribution of nanomaterials in the environment.
