Chelate-free metal ion binding and heat-induced radiolabeling of iron oxide nanoparticles.
A novel reaction for chelate-free, heat-induced metal ion binding and radiolabeling of ultra-small paramagnetic iron oxide nanoparticles (USPIOs) has been established. Radiochemical and non-radioactive labeling studies demonstrated that the reaction has a wide chemical scope and is applicable to p-, d- and f-block metal ions with varying ionic sizes and formal oxidation states from 2+ to 4+. Ra...

متن کاملHistopathological effects of quercetin on liver tissue damage induced by iron oxide and iron oxide nanoparticles in Wistar rats
Introduction: Industrial and environmental pollution, excessive iron supplementation and blood transfusion are among the factors that may cause iron toxicity. Therefore, it is necessary to identify the mechanisms influencing or protecting against iron toxicity. The present study aimed to investigate the protective effects of quercetin as an antioxidant on hepatotoxicity induced by iron oxide an...
متن کاملIncreasing the Shelf Life of Milk by Metal Oxide Nanoparticles and Mild Heat
Background: The spread of pathogenic microorganisms in food and beverage and their resistance to antibiotics have raised major concerns for public health. The aim of this study was to investigate the antimicrobial activity of various metal oxide nanoparticles (NPs) including zinc oxide (ZnO), magnesium oxide (MgO), and iron oxide (Fe2O3) NPs against Staphylococcus aureus (S. aureus) and Esch...
متن کاملNew surface radiolabeling schemes of super paramagnetic iron oxide nanoparticles (SPIONs) for biodistribution studies.
Nanomaterial based drug delivery systems allow for the independent tuning of the surface chemical and physical properties that affect their biodistribution in vivo and the therapeutic payloads that they are intended to deliver. Additionally, the added therapeutic and diagnostic value of their inherent material properties often provides extra functionality. Iron based nanomaterials with their ma...
