Iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. We aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt. Fifteen adult rabbits were divided into 3 groups o...
different types of iron oxides deposits have been identified along the khaf – dorouneh volcanic and plutonic belt in north east of iran. kuh-e-zar is one of these ore deposits known as fe- oxide gold deposit. the main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the etm+ data. data processing has been done by envi (environment for visualizing...
Objective- The healing effect of chitosan supported cerium oxide nanoparticles (nano-CeO2) on cutaneous experimental excisional wound infected with pseudomonas aeruginosa was studied in rat. Design- Experimental Study. Animals- Sixty male albino rats. Procedures- The chitosan supported nano-CeO2 hydrogel was prepared and characterized using Fourier-transform infrared spectro...
Chitosan (CS) functionalization over nanomaterials has gained more attention in the biomedical field due to their biocompatibility, biodegradability, and enhanced properties. In present study, CS functionalized iron (II) oxide nanocomposite (CS/FeO NC) was prepared using Sida acuta leaf extract by a facile eco-friendly green chemistry route. Phyto-compounds of S. were used as reductant prepare ...
Based on chelation effect between iron ions and amino groups of chitosan, in situ mineralization of magnetite nanoparticles in chitosan hydrogel under ambient conditions was proposed. The chelation effect between iron ions and amino groups in CS-Fe complex, which led to that chitosan hydrogel exerted a crucial control on the magnetite mineralization, was proved by X-ray photoelectron spectrum. ...
Aims In recent years, iron oxide nanoparticles have shown incredible possibilities in biomedical applications due to their non-toxic function in biological systems. Furthermore, these nanoparticles have multifunctional applications, such as antibacterial, antifungal, and anticancer effects in medicine due to their magnetic properties. Methods & Materials In this article, 49 articles related t...
A hybrid nanocomposite composed of polyaniline-polystyrene-chitosan/zinc oxide was prepared via a simple in situ polymerization method. The synthesized copolymers were analyzed using Fourier Transform InfraRed (FT-IR), and UltraViolet-Visible (UV–Vis) spectroscopies, ThermoGravimetric Analysis (TGA), and Field Emission Scanning Electron Microscopy (FE-SEM), X-ray diffracti...
background: the most common metal used in the body is iron and since it may produce ros, it could potentially be a dangerous substance. objectives: regarding the side effects of nanomaterials such as nano iron particles and possibility of environmental contamination including air pollution with nanoscale iron particle, this study was designed to compare the effects of conventional iron oxide wi...
In order to study the effects of supplementary irrigation and nano iron oxide on the grain yield, and some physiological and biochemical traits of wheat (Triticum aestivum L.) under rain fed conditions, a factorial experiment was conducted based on a randomized complete block design with three replications in Agricultural Research Station of Ardabil, Northwest of Iran, in 2016. Factors inclu...
