Abstract :
Magnetosensitive nanocomposites on the basis
of monodomain magnetite Fe3O4/meso-2,3-dimercaptosuccinic
acid, Fe3O4/c-aminopropyltriethoxysilane, Fe3O4/
polyacrylamide, Fe3O4/hydroxyapatite were synthesized.
Size distribution of magnetite nanoparticles in ensemble and
their magnetic properties were studied. It has been shown
that the magnetization curve of the liquid containing monodomain
magnetite has a form that is characteristic for superparamagnetics,
and its calculations in the framework of
Langeven’s paramagnetism theory match satisfactorily to
the experimental results. The highest adsorption parameters
were observed for magnetosensitive nanocomposites Fe3O4/
polyacrylamide and Fe3O4/c-aminopropyltriethoxysilane.
Prospects of the studied nanostructures for medicobiological
and technical applications as adsorbents of cis-dichlorodiammineplatinum
were shown.
