nowadays nanotechnology as a new direction of science allows us to develop therapeutic methods of the endogenous intoxication syndrome and to create a new class of biocompatible sorbents. in ukraine first preparations of medical nanotechnology were produced and patented in 1998. these are ikbb (intracorporeal biocorrector), magnet-controlled sorbent (mcs-b), and micromage-b. the preparations ar...

Behavioural studies underpin the weight of experimental evidence for the existence of a magnetic sense in animals. In contrast, studies aimed at understanding the mechanistic basis of magnetoreception by determining the anatomical location, structure and function of sensory cells have been inconclusive. In this review, studies attempting to demonstrate the existence of a magnetoreceptor based o...

magnetic cofe2o4 nanoparticles were synthesized via a simple chemical reaction using precipitation method. the obtained materials consist of ferrite particles with average diameter of 25 nm. the effect of different surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. scanning electron microscopy was used to study the structure and particle size o...

background: magnetic nanoparticles in a variable magnetic field are able to produce heat. this heat (42-45°c) has more selective effect on fast dividing cancer cells than normal tissues. methods: in this work magnetite nanoparticles have been prepared via co-precipitation and phase identification was performed by powder x-ray diffraction (xrd). magnetic parameters of the prepared nanoparticles ...

Particle transport and its effect on the plasma density distribution remains an important, unresolved issue in magnetic fusion plasmas [1]. Fluctuating magnetic fields can arise from global tearing instabilities that often underlie the sawtooth oscillation [2] and lead to plasma relaxation [3]. Furthermore, magnetic fluctuations are also generated by energetic particles associated with non-indu...

We describe the concept of magnetic particle-scanning for on-chip detection of biomolecules: a magnetic particle, carrying a low number of antigens (Ag's) (down to a single molecule), is transported by hydrodynamic forces and is subjected to successive stochastic reorientations in an engineered magnetic energy landscape. The latter consists of a pattern of substrate-bound small magnetic particl...
