A scalable technique for making silica coatings with embedded two-dimensional arrays of iron oxide nanoparticles is presented. The iron oxide nanoparticle arrays were formed by depositing quasi-crystalline ferritin layers, an iron storage protein with an iron oxide mineral core, on solid substrates by a spread-coating technique based on evaporation-induced convective assembly. The layer of prot...
The iron nanoparticle technology has received considerable attention for its potential applications in groundwater treatment and site remediation. Recent studies have demonstrated the efficacy of zero-valent iron nanoparticles for the transformation of halogenated organic contaminants and heavy metals. In this work, we present a systematic characterization of the iron nanoparticles prepared wit...
Of different types of bio-compatible nanoparticles, iron oxide nanoparticle has attracted attention for its applications especially in medicine and magnetic resonance imaging (MRI). We decided to study histological changes in testis and spermatogenesis in mature male mice that are affected by ironoxide nanoparticles (Fe2O3) during fetal period. In this study, the mice were divided into three e...
The use of engineered nanoparticles in food and pharmaceuticals is expected to increase, but the impact of chronic oral exposure to nanoparticles on human health remains unknown. Here, we show that chronic and acute oral exposure to polystyrene nanoparticles can influence iron uptake and iron transport in an in vitro model of the intestinal epithelium and an in vivo chicken intestinal loop mode...
To obtain the optimal 1:1 composition of FePt alloy nanomaterials by polyol synthesis, the iron precursor (iron pentacarbonyl, Fe(CO)5) must be used in excess, because the Fe(CO)5 exists in the vapor phase at the typical temperatures used for FePt synthesis and cannot be consumed completely. Fabrication of Fe3O4 nanoparticles by consuming the excess iron precursor was an effective strategy to m...
Introduction: hyperthermia using different methods such as microwave and magnetic waves is one of the methods to treat cancer. In this method, iron and magnetic nanoparticles are used to increase the temperature and increase the effect of hyperthermia as auxiliary treatment with chemotherapy and radiotherapy. In this study, the role of iron and magnetic nanoparticles have been ...
