The current work aims to synthesize highly fluorescent and surface-functionalized gadolinium oxide nanoparticles (Gd2O3 NPs) with (3-mercaptopropyl) trimethoxysilane (MPTMS). surface modification of Gd2O3 MPTMS enhanced the stability solubility nanoprobe in aqueous media. size was controlled 7 ± 1 nm using coating. These valued points made MPTMS@Gd2O3 as economical, sensitive, selective a quick...

We developed biofunctionalized nanoparticles with magnetic properties by immobilizing diethyleneglycol (DEG) on Gd2O3, and PEGilation of small particulate gadolinium oxide (SPGO) with two methoxy-polyethyleneglycol-silane (mPEG-Silane 550 and 2000 Da) using a new supervised polyol route, described recently. In conjunction to the previous study to achieve a high quality synthesis and increase in...

Single-crystal Gd2O3 films were grown epitaxially on GaAs~100! substrate. From the single-crystal momentum space analysis on four different samples, 185, 45, 25, and 18 Å thick, a Mn2O3 isomorphous cubic structure is identified. The Gd2O3 film aligns its twofold ~110! axis with the fourfold ~100! surface normal of the substrate, while aligning its @001# and @ 1̄10# axes with the @011# and @011̄# ...

Introduction: Recent advances in nanoscience and biomedicine have attracted tremendous attention over the past decade to design and construct multifunctional nanoparticles that combine targeting, therapeutic, and diagnostic functions with a single platform to overcome the problems of conventional techniques for diagnosis and therapy with minimal toxicity.   Materials ...

Gd2O3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. First, Gd(OH)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (PC) mode. The deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. The electrodeposited precursor was the...

the mononuclear gd(iii) complex, [gd(l)3(h2o)5] (where l is alizarin yellow r (nac13h8n3o5)), has been prepared in h2o under reflux condition. the gd(iii) complex has been characterized by elemental analysis and spectroscopic methods (uv–vis and ft–ir). the gd2o3 nanoparticles were prepared by the calcination of the gd(iii) complex in air at different temperatures up to 600 °c for 2 h. the calc...

Mesoporous-silica-coated Gd2O3:Eu/silica nanoparticles were synthesized by a multistep chemical process and characterized by XRD, TEM and N2 adsorption/desorption isotherms in terms of size, morphology and porosity. The core Gd2O3:Eu obtained by this method was highly luminescent upon excitation, giving the function of cell imaging upon incubation with the human cervical carcinoma (HeLa) cells....
