The article presents magnetoliposomes as potential carriers of doxorubicin. The magnetic properties of nanoparticles embedded in liposomes enable the targeting of drug-loaded carriers to cancer cells and subsequent release of their payload using an external alternating magnetic field as a trigger. The cytotoxicity of empty and doxorubicin-loaded magnetoliposomes in the absence and after exposure to magnetic field was evaluated in cancerous and normal breast cells. The characteristic shows the carrier with size distribution <130 nm, slightly negative zeta potential and polydispersity index <0.2. Doxorubicin was encapsulated in magnetoliposomes with an efficiency of 31 % and released in the presence of an alternating magnetic field at 50 %. Magnetoliposomes with drug provided high cytotoxic effect on tumor cells and low cytotoxic effect on normal cells. The research conducted in this article may indicate the potential application of the studied magnetoliposomes in release of drugs under the influence of magnetic field in cancer cells.
