Two types of superparamagnetic iron oxide nanoparticles designed for mesenchymal stem cell labeling and magnetic resonance imaging in vivo tracking were constructed in our laboratories. Both types of nanoparticles have an iron oxide core and a thin layer of silica coating, one of them has additional surface modification with amine. The overall particle size was around 8 nanometers. The in vitro study...
The elastic modulus and hardness of several microstructure components of dry bovine vertebrae and tibia have been investigated in the longitude and transverse directions using nanoindentation. The elastic modulus for the osteons and the interstitial lamellae in the longitude direction were found to be (24.7±2.5) GPa and (30.1±2.4) GPa. As it's difficult to distinguish osteons from interstitial lamellae...
