High-sensitive immunoanalytical platform based on iron oxide nanoparticles and magnetic beads containing composite nanomaterials

Kinetic characteristics of the hard-magnetic particles containing composite nanomaterials and soft magnetic iron oxide particles were studied by the spectral-phase interferometry to achieve the maximum dynamic range and minimal non-specific binding in a novel bioanalytical platform. In the platform, the former particles are used as a mobile solid phase controlled by an external field, while the latter - as nanolabels.
