David Clases leads the NanoMicroLab and aims to advance the characterisation and application of nano- and microscaled materials. The focus of his group is mainly based on elemental mass spectrometry and its application for single particle analyses as well as imaging approaches. Single particle approaches enable the establishment of multidimensional models providing perspectives on particle number concentrations, size/mass distributions as well as elemental compositions in individual particles. Currently these approaches are applied to pinpoint and characterise elusive structures in the environment. Elemental imaging, however, enables the quantitative resolution of elemental distribution in complex systems and is mainly applied to investigate integrated and discrete structures in biological specimens.
