A process for the preparation of unilamellar vesicles, wherein a unilamellar vesicle comprises an amphiphilic membrane enclosing an aqueous core; and compositions comprising unilamellar vesicles.

The process comprises providing a primary emulsion comprising an amphiphilic membrane forming component, a first aqueous phase W1 and a first oil phase O1. The first aqueous phase W1 is dispersed as droplets in the oil phase O1 such that the primary emulsion is a water-in-oil emulsion. The primary emulsion comprises droplets having a mean diameter of less than 1000 nm.

The process comprises combining the primary emulsion with a second aqueous phase W2 to produce a secondary emulsion that is a water-in-oil-in-water emulsion; dewetting to yield unilamellar vesicles in the secondary emulsion; and isolating the unilamellar vesicles.

Multisomes: encapsulated droplet networks

The invention provides a droplet encapsulate comprising: a drop of a hydrophobic medium; a peripheral layer of non-polymeric amphipathic molecules around the surface of the drop; and an aqueous droplet within the peripheral layer, the aqueous droplet comprising: (a) an aqueous medium and (b) an outer layer of non-polymeric amphipathic molecules around the surface of the aqueous medium. The invention also provides processes for preparing the droplet encapsulates. Various uses of the droplet encapsulates are also described, including their use as drug delivery vehicles, in synthetic biology, and in the study of membrane proteins.

DRUG DELIVERY PLATFORM USING W/O/W-TYPE TRIOLEIN EMULSION PROMOTIVE OF BLOOD-BRAIN BARRIER OPENING

The present invention relates to a composition for drug delivery to a tissue having a tight junction comprising a triolein emulsion of an internal water phase/oil phase/external water phase (Water/Oil/Water, W/O/W) structure in which oil droplet comprises triolein and water droplets are enclosed in the oil droplet, as an active ingredient, and a method of preparing the same, and the triolein emulsion of the W/O/W-type structure according to the present invention has excellent safety because it retains the BBB opening activity of triolein as it is and the water droplets are enclosed in the oil droplets and contain surfactants and can further enclose fat-soluble drugs in the oil droplets and thus it can more effectively deliver drugs to tissues having tight junctions such as the brain, testicles, and retina.
