We here report a multimodal investigation of the action of high density lipoprotein (HDL) in atherosclerosis using a HDL mimicking iron oxide nanoparticle. These particles are detectable by MRI, optical techniques and transmission electron microscopy, allowing their visualization at the anatomical, cellular and sub-cellular level. The HDL nanoparticles were applied in vitro and on atherosclerotic and wild type mice in vivo and successfully enabled us to study lipoprotein function.
