title: [Concentration-dependent effects of magnetic accumulation of ligand-binding microparticles and ferritin aggregates].
abstract: A method for measuring the magnetic susceptibility of microparticles of a suspension from the thickness of the layer deposited on the surface of a magnetized wire was developed. The magnetic accumulation was registered by means of a photodetector, by measuring the amplitude and spectrum of fluctuations of the intensity of scattered light. This was used as the basis for the development of a biosensor and biochips.
