In Vivo Toxicity of Intravenously Administered Silica and Silicon Nanoparticles
Both silicon and silica nanoparticles (SiNPs and SiO2NPs, respectively) are currently considered to be promising carriers for targeted drug delivery. However, the available data on their in vivo toxicity are limited. The present study was aimed at investigation of SiNP and SiO2NP (mean diameter 10 and 13 nm, respectively) toxicity using both morphological and functional criteria. Hematological ...
متن کاملAcute Toxicity of Intravenously Administered Titanium Dioxide Nanoparticles in Mice
BACKGROUND With a wide range of applications, titanium dioxide (TiO₂) nanoparticles (NPs) are manufactured worldwide in large quantities. Recently, in the field of nanomedicine, intravenous injection of TiO₂ nanoparticulate carriers directly into the bloodstream has raised public concerns on their toxicity to humans. METHODS In this study, mice were injected intravenously with a single dose o...
متن کاملAcute Toxicity of Amorphous Silica Nanoparticles in Intravenously Exposed ICR Mice
This study aimed to evaluate the acute toxicity of intravenously administrated amorphous silica nanoparticles (SNPs) in mice. The lethal dose, 50 (LD50), of intravenously administrated SNPs was calculated in mice using Dixon's up-and-down method (262.45±33.78 mg/kg). The acute toxicity was evaluated at 14 d after intravenous injection of SNPs at 29.5, 103.5 and 177.5 mg/kg in mice. A silicon co...
متن کاملToxicity of colloidal silica nanoparticles administered orally for 90 days in rats
This study was undertaken to investigate the potential toxicity and establish the no observed adverse effect level (NOAEL) and target organ(s) of negatively charged colloidal silica particles of different sizes, ie, SiO2 (EN20(-)) (20 nm) or SiO2 (EN100(-)) 2(100 nm), administered by gavage in Sprague-Dawley rats. After verification of the physicochemical properties of the SiO2 particles to be ...
متن کاملIn vivo Toxicity Investigation of Magnesium Oxide Nanoparticles in Rat for Environmental and Biomedical Applications
Background: Magnesium oxide nanoparticles are characterized with a wide variety of applications and are mass-produced throughout the world. However, questions remain regarding their safety. There has been paucity of toxicology research on their side effects, especially under in vivo conditions. Objectives: The present paper aims at evaluating the...
