It was also found that the presence of some metal ions and borates can effectively accelerate the hydrothermal carbonization of starch, which shortens the reaction time to some hours. Thus, iron ions and iron oxide nanoparticles were shown to effectively catalyze the hydrothermal carbonization of starch (< 200 °C) and also had a significant influence on the morphology of the formed carbon nanomaterials [10]. In the presence of Fe2+ ions, both hollow and massive carbon microspheres could be obtained. In contrast, the presence of Fe203 nanoparticles leads to very fine, rope-like carbon nanostructures, reminding one of disordered carbon nanotubes.

For MRI or histological tracking of MSG in vivo, cultured mesenchymal stem cells were prelabeled for 24 hours with carboxy-dextran-coated iron oxide nanoparticles (Resovist, Schering, Berlin, Germany) (Ittrich et al, 2005 Lange et al., 2005b). 

Figure 1. MSC accumulate within the scar area. MSC fed with superparamagnetic iron oxide nanoparticles and injected into the border zone of infarcted myocardinm migrate into the infracted area.

In in vitro experiments, MSC developed an early myogenic phenotype (Jaquet et al, 2005), however we did not succeed in generating self-contracting or even twitching (cardio-) myoc54es (not shown). Our results reveal that MSC are able to survive at least 10 weeks within the rat myocardium. When paramagnetic iron oxide nanoparticles were incorporated into rMSC prior to transplantation, cells within the myocardial scar area could be detected in our study. This could be some evidence that rMSC are able to migrate into the scar from the site of injection. 

The PEDM is able to explain the anomalous relaxation of solutions of ferritin and akaganeite particles, especially its linear dependence with Bq, the external magnetic field. The model is compatible with the observed dependence of the rate on pH. The relaxation rate predicted by the PEDM is proportional to the number of adsorption sites per particle (q) the values deduced for q from the adjustment of the model to experimental results (from NMR and magnetometry in solutions) are reasonable for hydrated iron oxide nanoparticles (63). 

Klupinski et al. (2004) report a laboratory experiment on the degradation of a fungicide, pentachloronitrobenzene (C Cl NO ), in the presence of goethite and iron oxide nanoparticles this study was intended to illustrate the fate of organic agrochemical contaminants in an iron-rich subsurface. To compare the effects of iron with and without a mineral presence, experiments were performed using...
