Magnetically responsive liposomes, comprising magnetic nanoparticles encapsulated within liposomes, are acknowledged for their versatility in drug and gene delivery, cancer diagnosis, and treatment. With their chemical functionality, biocompatibility, and potential for cancer hyperthermia therapy, they represent a groundbreaking delivery system. As a contract service provider, CD Formulation leverages advanced technology and expertise to engineer customized magnetic nanoparticle delivery systems, focusing on magnetic liposomes.
Magnetic-targeted liposomes use magnetic material to guide active substances into specific tissues, increasing drug concentration in the target area. Releasing drugs through the use of magnetic fields becomes possible by incorporating magnetic nanoparticles such as iron oxide nanoparticles (IONPs). The process involves exposing the MNP-loaded liposome system to alternating magnetic fields (AMF) to trigger drug release via a thermal process generated by the MNPs. Magnetically nanoparticles can be arranged differently in the structure of liposomes depending on the nature of their surface.

Magnetically responsive liposomes are generated through the combination of drug-loaded liposomes with a lipid mixture, followed by coating them with magnetic nanoparticles. We offer a bottom-up method (construction of nanostructures by individual atoms or molecules), as well as a top-down method for developing magnetic liposomes, including (grinding microstructures down to the nanoscale).
Magnetically responsive liposomes are incorporated with magnetic carrier materials, such as magnetic Fe3O4, with a directional effect on the lesion site under the action of an external magnetic field, because of their good drug-carrying and targeting properties. At present, we can customize magnetic liposomes, including As2O3 nanomagnetic liposomes, MnxZn(1-x)Fe2O4 magnetic liposomes, multi-response stimulation liposomes, paramagnetic long cycle nanoliposomes, a variety of modified magnetic liposomes, etc.
We can provide a series of modification services, including modification with chitosan, mannitol, and cell-penetrating peptide (TAT).

Results: In this study, authors explore the unique properties of magnetically responsive hydrogels to create a liposome hydrogel delivery platform that can precisely regulate drug release based on these hydrogels' mechanical responses upon exposure to an external magnetic field. The DPPC: FA liposomes loaded with ferulic acid (FA) were encapsulated into magnetically responsive gelatin hydrogels containing dispersed magnetic iron oxide nanoparticles (MNPs) (i.e., magnetically responsive gelatin). They developed a magnetically responsive liposome hydrogel delivery system, which provides the possibility of magnetically activating these liposome platforms for non-thermal-related drug delivery, paving the way for the development of novel and more effective applications of MLV and liposome delivery systems in biomedicine.
