Аннотация: Superparamagnetic ferrihydrite powders with average nanoparticle sizes of 2.5 nm produced by the chemical deposition method. Static and dynamic magnetic properties are measured. As a result of ultrasonic treatment in the cavitation regime of suspensions of ferrihydrite powders in a solution of the albumin protein, the Fe ions are reduced to the metallic state. A sol of ferrihydrite nanoparticles is prepared in an aqueous solution of arabinogalactan polysaccharide. © Published under licence by IOP Publishing Ltd.

Примечания : Cited References:12. - The reported study was carried out with the financial support of the Russian Foundation for Fundamental Research, the Government of the Krasnoyarsk Territory, the Krasnoyarsk Territory Fund for Support of Scientific and Technical Activity in the framework of scientific Project No. 18-43-243003. This work was supported by the Council of the President of the Russian Federation for State Support of Young Scientists and Leading Scientific Schools (project no. MK-1263.2020.3).
Аннотация: In this work, magnetite nanoparticles coated with polysaccharides were synthesized. Arabinogalactan and chitosan were used as polysaccharides. The possibilities of immobilization of biospecific molecules on the surface of the obtained composites were studied. Experiments on covalent immobilization of biospecific molecules on magnetic nanoparticles coated with a polysaccharide showed a high density of immobilized molecules. This suggests the use of such materials in bioanalytical systems or as affinity sorbents. (c) 2020 Elsevier B.V. All rights reserved.
