Abstract
A method for forming vehicles for encapsulating passenger molecules which have been named solvent dilution microcarriers (SDMCs), and the products of this process, are disclosed which allows for immediate or delayed formation of the encapsulating vehicles following creation of a shelf-stable formed solution by dissolution of amphipathic bilayer-forming materials, appropriate solvent, and the passenger molecule, addition of aqueous solution, and further addition of solvent. The SDMCs are organized from the formed solution by dilution into an aqueous system, aerosolization, or rehydration in situ. A dressing material is formed by adsorbing said shelf-stable formed solution onto said material.
