SIMPLE PREPARATION AND SEPARATION OF MAGN ETOLIPOSOMES

Liposomes with incorporated magnetite (Fe3O4) particles of diameter si milar to 10 nm (magnetoliposomes) were studied from the point of view of their applications as carriers in the magnetic separations. The mag netite particles were prepared by coprecipitation of FeCl2 in the pres ence of an access of ammonia and then incorporated into the lipid bila yers of formed liposomes. The influence of magnetic field on their sep aration was studied spectrophotometrically. As has been shown, magneto liposomes represent a simple and cheap alternative to other commonly u sed but much more expensive commercial carriers.
