Ultrasmall paramagnetic Gd(2)O(3) nanoparticles have been developed as contrast agents for molecular and cellular preclinical MRI procedures. These small particles (mean diameter <5 nm) have the highest Gd density of all paramagnetic contrast agents. They generate strong positive contrast enhancement

Contrast media & molecular imaging, 8(1), 92-95 (2012-10-31)
In this communication, we demonstrate that there is an optimum gadolinium oxide (Gd(2)O(3)) nanoparticle size of 2.3 nm; in the presence of Gd(2)O(3) particles smaller and larger than this critical size, the spin-lattice relaxation rate (T(1) = 1/r(1)) of water

International journal of nanomedicine, 6, 3233-3240 (2012-01-10)
As the utility of magnetic resonance imaging (MRI) broadens, the importance of having specific and efficient contrast agents increases and in recent time there has been a huge development in the fields of molecular imaging and intracellular markers. Previous studies

Multifunctional materials for biological use have mostly been designed with composite or hybrid nanostructures in which two or more components are incorporated. The present work reports on a multifunctional biomaterial based on single-phased luminescent mesoporous lanthanide oxide nanoparticles that combine
Nikesh Gupta et al.
International journal of nanomedicine, 7, 5491-5500 (2012-12-13)
Mesoporous silica nanoparticles coencapsulating gadolinium oxide and horseradish peroxidase (HRP) have been synthesized in the aqueous core of sodium bis-(2-ethylhexyl) sulfosuccinate (AOT)-hexane-water reverse micelle. The average diameter of these silica particles is around 25 nm and the particles are spherical
