Abstract: Liposomes have been used in technologies in biological, pharmaceutical, medical and nutritional applications because they can offer biocompatibility, biodegradability, reduced toxicity, and capacity for size and surface modifications. Traditionally, liposomes are prepared by multiple steps. However, multiple steps of preparation may cause a number of problems including low yield, high polydispersity, and poor morphology. Here, we synthesized liposomes containing magnetic iron oxide nanoparticle using one-pot, single step synthesis under ultra-sonication. We optimized the lipid compositions, sonication power, concentration of iron oxide nanoparticles, and antibody conjugation using Cu-free click chemistry. Furthermore, we incorporated doxorubicin inside magnetic liposomes for combined antibody targeting and magnetic guidance. Fluorescence imaging and quantification confirmed that antibody conjugated magnetic liposome showed high cell specific targeting that was enhanced by magnetic delivery.
