Nano-Magnetic Materials. In most general terms, this project involves designing and studying new materials for novel electronic and magnetic devices. 5 Nanomagnetic Materials One of the guiding principles of nanotechnology is the observed changes in properties between bulk and nanoscale materials. A nanomagnet is a submicrometric system that presents spontaneous magnetic order Nanomagnet. From Wikipedia, the Nature Materials. 13 (8): –

The topological nature of these textures prevents them from untangling and thus creates stable magnetic bits that nanomagnetic materials ultimately be used for information storage.
Nanomagnetic Materials: A review
We currently grow nanolayers of chiral magnets by molecular beam epitaxy and explore the influence nanomagnetic materials strain and nanoscale size on the magnetic structure. Another potential treatment of cancer nanomagnetic materials attaching magnetic nanoparticles to free-floating cancer cells, allowing them to be captured and carried out of the body.
The treatment has been tested in the laboratory on mice and will be looked at in survival studies.
Blood can be inserted onto a microfluidic chip with magnetic nanoparticles in it. These magnetic nanoparticles nanomagnetic materials trapped inside due to an externally applied magnetic field as the blood is free to nanomagnetic materials through.
The magnetic nanoparticles are coated with antibodies targeting cancer cells or proteins.

The magnetic nanoparticles can be recovered and the attached cancer-associated molecules can be assayed to test for their existence. Magnetic nanomagnetic materials can be conjugated with carbohydrates and used for detection of bacteria.
Iron oxide particles have been used for the detection of Nanomagnetic materials negative nanomagnetic materials like Escherichia coli and for detection of Gram positive bacteria like Streptococcus suis   Magnetic immunoassay[ edit ] Magnetic immunoassay  MIA is a novel type of diagnostic immunoassay utilizing magnetic nanobeads 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 nanomagnetic materials label is conjugated to one element of the pair. The presence of magnetic nanobeads is then detected by a magnetic reader magnetometer which measures the magnetic field change induced by the beads.
The signal measured by the magnetometer is proportional to the analyte virus, toxin, bacteria, cardiac marker,etc.
Waste water treatment[ edit ] Thanks to the easy separation by applying a magnetic field nanomagnetic materials the very large surface to volume ratiomagnetic nanoparticles have a potential for treatment of contaminated water. At larger temperatures, the magnetization undergoes random thermal fluctuations superparamagnetism which present a limit for the use of nanomagnets nanomagnetic materials permanent information storage.
Canonical examples of nanomagnets are grains   of ferromagnetic metals ironcobaltand nickel and single-molecule magnets. The ultimate limit in miniaturization of nanomagnets was achieved in Nanomagnetism includes the artificial structuring of magnetic materials on a sub micron level and natural nanomagnetic materials magnetic entities such as molecules and clusters.
