Abstract
The present invention discloses a method for preparing alginate nanocapsules, including the steps of: (a) forming a water-in-oil emulsion including an alginate in water, an oil, and at least one nonionic surfactant; and (b) separating the aqueous phase and oil phase to obtain the semisolid form alginate nanocapsules; and (c) by ionically crosslinking the alginate with calcium ions to obtain a colloidal form of calcium alginate nanocapsules for drug delivery.
