Coacervate vesicles assembled by liquid–liquid phase separation improve delivery of biopharmaceuticals

Natural vesicles typically consist of a lipid membrane enclosing substances. Now a coacervate vesicle formed by liquid–liquid phase separation of cholesterol-modified DNA and histones has been developed. Unlike traditional vesicles, these lack a membrane and feature a high-density liquid layer around a water-filled cavity, offering enhanced kinetic stability and potential as a biopharmaceutical delivery system.
