Stabilized magnetic cerasomes for drug delivery

Area of Science:

• Biomaterials Science
• Nanotechnology
• Oncology

Background:

• Cerasomes offer a promising drug delivery platform due to their stability and biocompatibility.
• Developing targeted drug delivery systems is crucial for improving cancer therapy efficacy and reducing side effects.

Purpose of the Study:

• To construct doxorubicin hydrochloride (DOX)-loaded magnetic cerasomes (DLMCs) incorporating hydrophobic Fe3O4 nanoparticles (NPs).
• To evaluate the physicochemical properties, drug loading, release behavior, and anticancer efficacy of DLMCs.
• To investigate the potential of magnetic targeting for enhanced cancer cell uptake and killing.

Main Methods:

• Facile one-step construction of DLMCs by co-encapsulating Fe3O4 NPs and DOX within cerasomes.
• Characterization of DLMCs for Fe3O4 loading content, superparamagnetism, encapsulation efficiency, and drug loading.
• Assessment of storage stability and in vitro sustained drug release profiles.
• In vitro cellular uptake studies using cancer cells under external magnetic field application.
• Evaluation of the in vitro cytotoxicity of DLMCs against cancer cells.

Main Results:

• DLMCs were successfully synthesized with optimal Fe3O4 loading at a 4:1 Fe3O4/lipid molar ratio.
• DLMCs exhibited high superparamagnetism, strong magnetic field response, high encapsulation efficiency (43.4 ± 4.7%), and drug loading (3.2 ± 1.3%).
• Compared to liposomes, DLMCs showed superior storage stability and sustained drug release.
• Magnetic field application significantly enhanced DLMC uptake by cancer cells, leading to improved tumor cell killing.

Conclusions:

• Magnetic cerasomes are effective carriers for co-delivery of Fe3O4 NPs and DOX.
• DLMCs demonstrate enhanced stability, sustained release, and magnetically targeted delivery.
• The magnetic targeting strategy significantly improves drug delivery efficiency and anticancer activity, highlighting the potential of magnetic cerasomes for cancer therapy.
