Abstract: Methods for making particles, such as nanoparticles, devices useful in the methods, and particles made by the method are described herein. The methods involves the use of microfluidic device, such that upon mixing solutions of the materials to form the particles (or a solution of the material or materials to form the particles and a non-solvent for the material or materials) at least two symmetrical microvortices are formed simultaneously. The method can be used to prepare polymeric or non-polymeric particles and hybrid particles, such as lipid-polymer hybrid particles, as well as such particles containing one or more agents associated with the particles.

Abstract: The invention provides a use of a long-circulating microvesicle comprising a sterol, partially synthetic or wholly synthetic vesicle-forming phospholipids, and a corticosteroid in water soluble form, which microvesicle has a mean particle diameter size range of between about 75 and 150 nm and which microvesicle is non-charged or negatively charged at physiological conditions, for the preparation of a medicament for the treatment of atherosclerosis and/or cardiovascular disease. A method for treating a subject suffering from, or at risk of suffering from, atherosclerosis and/or cardiovascular disease, comprising administering to said subject a therapeutically effective amount of such long-circulating microvesicles is also provided.
