Silicon Nanoparticles As Pubmed Central Pmc

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.

Nanoparticle Wikipedia

A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres nm in diameter. The term is sometimes used for larger particles, up to 500 nm, citation needed or fibers and tubes that are less than 100 nm in only two directions. Nanoparticles are usually distinguished from 34fine particles34, sized between 100 and 2500 nm, and 34coarse
