Introduction: Gd (III) ion has been known to be the best metal ion in the periodic table that can be used as a T1 MRI contrast agent. Gadolinium have 7 unpaired electrons and these electrons can make magnetic area. No other metal ions possess unpaired electron more than this. CAs based on the element Gd are classified as “positive”, by opposition to “negative” CAs. Nowadays, G...

Hyperspectral microscopy is an intriguing technique combining spectroscopy with optical that can be used to simultaneously obtain spectral and spatial information. The relevance of hyperspectral imaging in biomedical applications such as the monitoring bioimaging agents, identification pathogens cancerous cells, cellular uptake nanoparticles has emerged recently, due recent advances reconstruct...

We studied the early stages of Gd2O3 epitaxy on Si(111) in real time by synchrotron-based, high-resolution X-ray diffraction and by reflection high-energy electron diffraction. A comparison between model calculations and the measured X-ray scattering, and the change of reflection high-energy electron diffraction patterns both indicate that the growth begins without forming a three-dimensional c...

Surface-coating polymers contribute to nanoparticle-based magnetic resonance imaging (MRI) contrast agents because they can affect the relaxometric properties of nanoparticles. In this study, polyaspartic acid (PASA)-coated ultrasmall Gd2O3 nanoparticles with an average particle diameter 2.0 nm were synthesized using one-pot polyol method. The exhibited r1 and r2 19.1 = 53.7 s−1mM−1, respective...

Gadolinium oxide (Gd2O3), which can be used as a T1-weighted magnetic resonance imaging (MRI) contrast agent, has attracted intense attention in recent years. In this paper, ligand-free monoclinic Gd2O3 nanocrystals of 7.1 nm in diameter are synthesized by a simple and green approach, namely microsecond laser ablation of a gadolinium (Gd) target in deionized water. These nanocrystals obtain hig...

Gadolinium (Gd) is a unique and powerful element in chemistry and biomedicine which can be applied simultaneously to magnetic resonance imaging (MRI), X-ray computed tomography (CT), and neutron capture therapy for cancers. This multifunctionality can be maximized using gadolinium oxide (Gd2O3) nanoparticles (GNPs) because of the large amount of Gd per GNP, making both diagnosis and therapy (i....
