Highly ordered self-assembly with large area of Fe(sub 3)O(sub 4) nanoparticles and the magnetic properties

Article Abstract:

A report is presented on the synthesis of monodispersive Fe(sub 3)O(sub 4) nanoparticles (NPs) with narrow size distribution, monolayer and multilayer self-assemblies of as-synthesized grains and the magnetic properties of NPs. Some magnetic properties enhanced by increasing interparticle distances and the saturation magnetization changed with temperature as expected were noticed.

Phenomenological predictions of cohesive energy and structural transition of nanoparticles

Article Abstract:

A liquid-drop model (LDM) predict the size-dependent cohesive energy (SDCE) of large nanoparticles and clusters quantitatively. The cohesive energy decreases linearly with the inverse of the particle size both for large nanoparticles and clusters though the slopes are different.

Magnetic iron oxide nanoparticles for biorecoginition: Evaluation of surface coverage and activity

Article Abstract:

A study was conducted on the surface coverage and the activity of the IgG antibodies on magnetic nanopaticles (MNPs). The results revealed that the surface coverage could be stoichiometrically adjusted with saturated surface occurring at ~36% of the theoretical limit.
