New Magnetic Colloidal Systems Based on Biomimetic Polycomplexes

This paper presents new colloidal systems that have prospects for use as carriers of medicinal compounds and are polymer complexes based on polyacrylic acid molecules of various molecular weights and biogenic polyamine, additionally modified with magnetic iron oxide nanoparticles. The main physicochemical characteristics of the resulting polycomplexes are determined. The possibility of incorporating a doxorubicin medicinal compound in the polycomplexes is demonstrated, and the magnetic properties of the polycomplexes functionalized with magnetic iron oxide nanoparticles are studied.
