Ultra small Gd2O3 nanoparticles: Absorption and emission properties

Ultrasmall NaGdF4 Nanodots for Efficient MR Angiography and Atherosclerotic Plaque Imaging

“…Meanwhile, the Fe 3+ ions are potentially toxic due to the possible fenton reactions via Fe 3+ /Fe 2+ cycling in bodies . Alternatively, though Gd 3+ ion exhibits better MRI performance than iron ion due to its more unpaired electrons, unfortunately, the potentially released free Gd 3+ ions might cause severe nephrogenic system fibrosis (NSF) syndrome in vivo . Therefore, the Gd 3+ ions leakage should be strictly prevented.…”

“…Ultasmall Gd containing NPs as MR CAs are not new, however, the chelating agent design to capture the potentially released Gd 3+ , their further bio‐application in medical imaging and systematically biocompatibility in vivo have not been reported to date. Compared with previous reported Gd 2 O 3 NPs, inorganic fluorides such as NaGdF 4 NPs hold a great promise as fluorescent host materials after doping of rare earth ions because of their high chemical stability and intrinsic low phonon energies . Moreover, these Gd 2 O 3 NPs have been synthesized in polyol or water media.…”

Gd2O3 nanoparticles: size‐dependent nuclear magnetic resonance

“…In synthesizing the gadolinium oxide nanoparticles we have used a slightly modified synthetic route reported earlier by us . In brief, 0.1921 g of citric acid (bought from UNIVAR, Australia) was thoroughly dissolved in 20 ml purified water in a sonic bath.…”

“…In order to find Gd 2 O 3 size‐dependent spin‐lattice relaxation of water protons, samples of gadolinium oxide in the size range 1.5–194.0 nm were prepared using a synthetic route similar to that we reported earlier (for the description of the synthesis route see the Experimental section).…”

Ethylene Glycol Functionalized Gadolinium Oxide Nanoparticles as a Potential Electrochemical Sensing Platform for Hydrazine and p-Nitrophenol

“…The current work has utilized the electron transport abilities, high electrical conductivity, and thermal stabilities of Gd 2 O 3 Nps for making effective material in electrochemical sensing for harmful pollutants [21][22][23]. To date, a diverse range of methodologies has been investigated for the preparation of Gd 2 O 3 Nps [24][25][26][27][28]. The available methods have generally required very high temperature reaction conditions and multistep processing for the synthesis of Gd 2 O 3 Nps.…”
