Gadolinium (Gd)-based contrasts remain one of the most accepted contrast agents for magnetic resonance imaging, which is among the world most recognized noninvasive techniques employed in clinical diagnosis of patients. At ionic state, Gd is considered toxic but less toxic in chelate form. A variety of nano-carriers, including gadolinium oxide (Gd2O3) nanoparticles have been used by researchers...
Poor toxicity characterization is one obstacle to the clinical deployment of Gd2O3@ SiO2 core-shell nanoparticles (Gd-NPs) for use as magnetic resonance (MR) imaging contrast agents. To date, there is no systematic toxicity data available for Gd-NPs prepared by laser ablation in liquid. In this article, we systematically studied the Gd-NPs' cytotoxicity, apoptosis in vitro, immunotoxicity, bloo...
1. growth of high dielectric constant oxides on InGaAs and GaN using molecular beam epitaxy (MBE) and atomic layer deposition (ALD) 2. structural studies on hetero-structures of nano-thick Al2O3, HfO2, and Ga2O3(Gd2O3)/ InGaAs (and GaN) using high-resolution x-ray reflectivity using in-situ/ex-situ high-resolution synchrotron radiation and high-resolution transmission electron microscopy 3. cor...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
