Chelator free gallium-68 radiolabelling of silica coated iron oxide nanorods via surface interactions.
The commercial availability of combined magnetic resonance imaging (MRI)/positron emission tomography (PET) scanners for clinical use has increased demand for easily prepared agents which offer signal or contrast in both modalities. Herein we describe a new class of silica coated iron-oxide nanorods (NRs) coated with polyethylene glycol (PEG) and/or a tetraazamacrocyclic chelator (DO3A). Studie...
متن کاملChelate-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 کاملLarge enhancements of magnetic anisotropy in oxide-free iron nanoparticles
Magnetic characterization of spherical, oxide-free, bcc iron nanoparticles synthesized with b-diketone surfactants has been performed. The results of this characterization, which included particles with diameters ranging between 2 and 5 nm show that the nanoparticles have an average anisotropy of 1.9 1070.3 10 J/m, which is more than an order of magnitude greater than the magnetocrystalline ani...
متن کاملPreparation of surface modified magnetic Iron Oxide nanoparticles and study of their colloidal behavior
In this work, we report synthesis of surface modified superparamagnetic iron oxide nanoparticles (SPION) by co-precipitation method using FeSO4.7H2O and Fe2(SO4)3.5H2O as precursors and trisodium citrate dihydrate as surfactant. Surface modification of the as prepared samples was performed in pot by sol-gel precipitation method u...
