Magnetic Nanoparticles

Magnetic Nanoparticles are a class of Nanoparticles which can be manipulated using magnetic field. The physical and chemical properties of magnetic Nanoparticles largely depend on the synthesis method and chemical structure. In most cases, the particles range from 1 to 100 nm in size and may display superparamagnetism.

Applications
a cMedical diagnostics and treatments
Magnetic Nanoparticles are used in an experimental cancer treatment called magnetic hyperthermia in which the fact that Nanoparticles heat when they are placed in an alternative magnetic field is used.

a cMagnetic immunoassay
Magnetic immunoassay is a novel type of diagnostic immunoassay utilizing magnetic beads as labels in lieu of conventional, enzymes, radioisotopes or fluorescent moieties. This assay involves the specific binding of an antibody to its antigen, where a magnetic label is conjugated to one element of the pair.

a cWaste water treatment
The easy separation by applying a magnetic field and the very large surface to volume ratio, magnetic Nanoparticles have a good potential for treatment of contaminated water

a cChemistry
Magnetic Nanoparticles are being used or have the potential use as a catalyst or catalyst supports. In chemistry, a catalyst support is the material, usually a solid with a high surface area, to which a catalyst is affixed. The reactivity of heterogeneous catalysts occurs at the surface atoms.
