Functionalized semiconductor nanoparticles of 110 nm diameters are formed from bulk material with Reactive High Energy Ball Milling (RHEBM).
Dec 22, 2009· Magnetic resonance imaging of hyperpolarized nuclei provides high image contrast with little or no background signal. To date, in-vivo applications of pre-hyperpolarized 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.
