Dec 22, 2009· Magnetic resonance imaging of hyperpolarized nuclei provides high image contrast with little or no background signal. To date, invivo applications of prehyperpolarized materials have been limited by relatively short nuclear spin relaxation times. Here, we investigate silicon nanoparticles as a new type of hyperpolarized magnetic resonance imaging agent.
In attrition, macro or microscale particles are ground in a ball mill, a planetary ball mill, or other sizereducing mechanism. The resulting particles are air classified to recover nanoparticles. In pyrolysis, a vaporous precursor (liquid or gas) is forced through an orifice at high pressure and burned.
