A method for encapsulating a material comprises the steps of choosing a material to encapsulate; placing the material into a material solvent to form a material solution; forming a primary emulsion of the material solution in an immiscible liquid medium that is immiscible with the material solvent, the material solution serving as the disperse phase and the immiscible liquid medium serving as the continuous phase of the primary emulsion, wherein the immiscible liquid medium contains an encapsulating agent dissolved therein, the encapsulating agent being capable of being crosslinked, polymerized, gelled or otherwise hardened or solidified; adding the primary emulsion as droplets into a crosslinking medium, and thereafter activating the crosslinking, polymerizing, gelling, hardening or solidifying of the encapsulating agent to envelope the material in a crosslinked, polymerized, gelled or otherwise hardened or solidified matrix forming the droplets into beads. |
