The ex-vivo endothelium-stent contact model allows measuring the impact of implants on the arterial tissue. The endothelium is directly exposed by inserting a wire made of the investigated material into the lumen of the aortic ring to mimic the contact between the coronary stent and the endothelium.

The cytokinesis-block micronucleus method allows assessing the presence of DNA damage at the chromosome level. It is an essential part of toxicology, because mutation is a crucial event in carcinogenesis. The capacity of inhaled particles to induce irreversible mutations in type II lung epithelial

The hemolysis assay remarkably predicts the inflammatory potential of inhaled particles. The capacity of particles to damage cellular membranes is a key property to predict their inflammatory potential upon inhalation. In macrophages and epithelial cells exposed to particles, alteration of the

HR MAS analysis of intact tissues consists in the metabolic profiling of entire tumor biopsies using high resolution NMR (nuclear magnetic resonance) using 1H and/or 13C MRS (magnetic resonance spectroscopy). The technique allows combination of metabolomic data with genomic or proteomic data, and
