OVERVIEW

  According to “The Project on Emerging Nanotechnologies,” more than 1300 consumer products contain nanoscale materials. Among them, a huge number of metal-containing nanoparticles can be found made of silver, zinc oxide, titanium dioxide, or gold. Due to the increasing use of nanoparticles, concerns exist with respect to their distribution in the environment and biological systems and their potential toxicological impact. Moreover, nanoparticle products need to be characterized in terms of their composition, particle sizes, and forms. Analytical methods are therefore required to monitor and characterize these nanoparticles. For the analysis of metallic or metal-containing nanoparticles, inductively coupled plasma-mass spectrometry (ICP-MS) is a very powerful technique. High sensitivity and selectivity are important properties to analyze the sought species, either qualitatively or quantitatively. Typically, ICP-MS is used in combination with a separation or fractionation technique or in the so-called single particle mode (spICP-MS). In this web seminar, we will discuss the basics of ICP-MS techniques for nanoparticle analysis and critically highlight key aspects of the development and use of these methods.

 
SPEAKERS

 

Jörg Bettmer, PhD
Assistant Professor
Department of Physical and Analytical Chemistry
University of Oviedo; Oviedo, Spain


Jörg Bettmer received his PhD in 1996 from the University of Münster, Germany, for his investigations of the speciation of mercury and lead, under Professor Karl Cammann. In 2000, he moved to the University of Mainz, Germany, to work in the group of Professor Klaus G. Heumann where he obtained the title of “habilitation” (venia legendi) in Analytical Chemistry in 2004. In 2007, he started as a Ramón y Cajal researcher at the University of Oviedo, Spain, in the group of Professor Alfredo Sanz-Medel. He became an assistant professor in 2012. His research work was granted with the Bunsen-Kirchhoff award and the Mattauch-Herzog award (together with Professor Dirk Schaumlöffel of CNRS in Pau, France) in 2007. He has published more than 60 research papers, review articles, and book chapters. His research interests are focused on the development and application of MS-based hyphenated techniques in the fields of elemental speciation, metallomics, and metal-based nanomaterial.
