Effect of arsenic source flow rate on the lattice defects in GaAsN grown by chemical beam epitaxy

Abstract

Tripositive gadolinium‐ion doped NIR‐to‐NIR upconverting paramagnetic nanoparticles are efficiently detected are NIR imaging techniques but can also provide efficient “positive” contrast in MRI. John A. Capobianco, Marc‐André Fortin, and co‐workers show that citrate‐coated nanoparticles present the lowest relaxometric ratios reported for NaGdF4 nanoparticle suspensions. IV‐injected nanoparticles evidence long blood retention times in mice while biodistribution studies show elimination through the reticuloendothelial and urinary systems.
