Nanoparticles

We are interested in determining naturally occurring nano-particles (NNP).

One route of research is the detoxification of mercury by forming an agglomeration with selenium in pilot whale livers, kidneys and brain. Here FFFF-ICP-MS and sp-ICP-MS as well as XANES/EXAFS were used to characterise these NNPs.

Natural nano-particles also occur in oil and gas condensate. These are mainly mercury sulfides, which are determined using FFFF with organic solvents coupled to ICP-MS.

Ongoing projects involve the identification of elemental selenium by fungi as part of the TeaSe project and the determination of natural nano-particles in biological tissues e.g. organs of whales and birds of prey. This information might be the key for the identification of detoxification mechanisms for elements like mercury and arsenic. Besides FFFF-ICP-MS, Laser-ablation ICP-MS and NanoSIMS will be used for these projects. Further we aim to work on the determination of nano-plastics in environmental and biological samples.
