Luc Faucher et al.
Contrast media & molecular imaging, 6(4), 209-218 (2011-08-24)
The majority of contrast agents used in magnetic resonance imaging (MRI) is based on the rare-earth element gadolinium. Gadolinium-based nanoparticles could find promising applications in pre-clinical diagnostic procedures of certain types of cancer, such as glioblastoma multiforme. This is one
Luc Faucher et al.
ACS applied materials & interfaces, 4(9), 4506-4515 (2012-07-28)
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
A T M Anishur Rahman et al.
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
Yu Kimura et al.
Advanced healthcare materials, 1(5), 657-660 (2012-11-28)
The synthesis, characterization, and functional evaluation of new size-controlled and biocompatible Gd(2) O(3) nanoparticles as a bimodal contrast agent for use in photoacoustic (PA) and magnetic resonance (MR) imaging are reported. These nanoparticles show a clear PA image by themselves
Aamir D Abid et al.
Particle and fibre toxicology, 10, 1-1 (2013-01-12)
The deposition, clearance and translocation of europium-doped gadolinium oxide nanoparticles in a mouse lung were investigated experimentally. Nanoparticles were synthesized by spray flame pyrolysis. The particle size, crystallinity and surface properties were characterized. Following instillation, the concentrations of particles in
