Abstract
A process is provided for releasably encapsulating a biological entity. The process comprises combining a solution of a surfactant in a non-polar solvent with a precursor material and the biological entity to form an emulsion. The emulsion comprises a polar phase dispersed in a non-polar phase, wherein the polar phase comprises the biological entity. The particles comprising the biological entity are then formed from the polar phase.
