Magnetic Nanoparticles in Magnetic Fluids

Magnetic fluids are stable colloidal systems of fine single-domain magnetic particles (for example Fe3O4, γ-Fe2O3, Co, MnFe2O4, etc.) that are suspended in liquid carrier such as water, mineral oil, damping oil, paraffin, kerosene and so on. The properties of magnetic fluids are well controlled by external magnetic field that gives broad possibilities for technical and biomedical applications. ...

Gelation of Magnetic Nanoparticles

Magnetic-mesoporous Janus nanoparticles.

Novel multifunctional magnetic-mesoporous Janus particles with controlled aspect ratio were developed by a simple one-step synthesis approach. Due to their superior magnetic properties and well-defined pore structures, these particles will be important in drug delivery, molecule targeting, cellular imaging, and as building blocks for the assembly of complex nanostructures.

Magnetic interactions between nanoparticles

We present a short overview of the influence of inter-particle interactions on the properties of magnetic nanoparticles. Strong magnetic dipole interactions between ferromagnetic or ferrimagnetic particles, that would be superparamagnetic if isolated, can result in a collective state of nanoparticles. This collective state has many similarities to spin-glasses. In samples of aggregated magnetic...
