Expertise

My expertise is the detection and characterization of nanoparticles in food and biological matrices. This analytical knowledge is essential for in vivo and in vitro studies that focus on the potential toxicological effect of nanoparticles in the context of oral exposure to humans. Further, the detection of nanoparticles in food, feed and food contact materials is required for future food control purposes. Whereas my current work focuses on safety aspects and toxicological effect of nanoparticles, future work is aiming at the potential use as delivery systems.

Analytical expertise:

Targeted sample preparation, e.g. by enzymatic or alkaline treatment
Analytical ultracentrifugation
Asymmetric flow field flow fractionation
Inductively coupled plasma mass spectrometry in conventional and single particle mode
Optical spectrometry and light scattering techniques (dynamic and multi angle)
Optical and electron microscopy (scanning and transmission electron microscopy including energy dispersive X-ray spectroscopy)

International experience

Participation in EU FP7 projects NanoLyse, Nanosolutions and NanoDefine (WP leader)
