Empa Two laboratories of Empa will contribute to the project. The particles-biology interactions laboratory has an in-depth knowhow and experience with various in-vitro assays, build up a profound experience with various imaging technologies (optical microscopy, analytical electron microscopy (SEM, TEM combined with EDX spectroscopy), Raman spectroscopy etc.) for the characterisation of different types of NP particles in cells and tissues. The team is very active in developing correlative approaches for obtaining complementary information about the interaction of the NPs and the biological environ-ment. Furthermore, the laboratory uses ICP-OES/MS on a routine basis to characterize NP composi-tion and to assess NP concentration in cells and tissues. The second Empa laboratory, the Center for X-ray Analytics, investigates NP size, shape, agglomeration and self-assembly behaviour investigating more specifically NP interactions in protein environments using different techniques, such as SAXS, WAXS, X-ray imaging (CT) and SANS. Their approach to investigate the dynamics of the NP protein corona building dynamics is unique and provides a profound insight into this essential topic.
