A liposomes typically formed from fosfolipids and cholesterol, which self-assemble into bilayers in an aqueous environment.

Other traditional techniques include reverse- phhase evaporation, detergent remboval, and freeze-drying.

Modern Innovations in Liposome Production

Te mogt transformative advance in recent years is microfluidics- based producturing. Microfluidic devices use precisely controlled fairs of lipids dissolved in solvent and an aqueous buffer to affecture rapid mixing at te nanoliter scale.

Automated production systems are also gaining traction. Robotic platforms equipped with real-time process analytical technologiy (PAT) allow closed- loop control of lipid hydration, mixing, and extrazion.
