Abstract


This work demonstrates studies of ferromagnetic nanoparticle functionalization by a lipid-like compound, cationic pyridine amphiphile derived from 1,4-dihydropyridine, 1,1'-{[3,5-bis(dodecyloxycarbonyl)-4-phenyl-1,4-dihydropyridine-2,6-diyl]dimethanediyl}dipyridinium dibromide, and determination of optimal conditions for the production of magnetoliposomes. The following methodologies, such as sonication, spontaneous swelling, and reverse-phase evaporation, were used for the preparation of liposomes. Ferrofluid containing γ-Fe2O3 nanoparticles with a positively charged surface was used for the preparation of magnetoliposomes. The obtained soft matter objects were studied by optical microscopy, transmission electron microscopy, and dynamic light scattering techniques. The optimal conditions for the production of magnetoliposomes were found by spontaneous swelling and reverse-phase evaporation methods using ferrofluid with positively charged γ-Fe2O3 nanoparticles and cationic 1,4-dihydropyridine derivative.
