Bifunctional Magnetic Luminescent Particles Based on Iron Oxide Nanoparticles Grafted with a Europium Silylated Bypiridine Tris(β-diketonate) Complex
(2016-01-01)
A new highly magnetic-luminescent nanocomposites has been synthesized by grafting luminescent europium complex comprising tris(b-diketone) and bypridine ligand modified with a silylil function group (Eu[(TTA)3(Bpy-Si)] ...
Magnetism of Nanosized Oxide Systems Investigated by Mössbauer Spectroscopy
(Springer, 2003-06)
The Mössbauer characterization of nanosized iron oxides is based on the dependence of the magnetic relaxation time on several parameters. Because the contributions of the magnetic anisotropy and of the particle volume ...

Catalytic properties of thioredoxin immobilized on superparamagnetic nanoparticles
(ELSEVIER SCIENCE INC, 2011)
Thioredoxin (Trx1), a very important protein for regulating intracellular redox reactions, was immobilized on iron oxide superparamagnetic nanoparticles previously coated with 3-aminopropyltriethoxysilane (APTS) via covalent ...
Design of super-paramagnetic bilayer films based on chitosan and sodium alginate
(Elsevier, 2021-12)
Bilayer films that combine chitosan and alginate, two natural polysaccharides, and magnetic iron oxide nanoparticles (MNPs) were obtained. Physical and microscopic observations revealed that chitosan and alginate interact ...
