|a Aqueous core colloidosomes encapsulating the enzyme amylase were manufactured with a shell comprising polymer latex particles of diameter 153 nm. The colloidosomes were sealed with calcium carbonate by precipitation between an inner phase of Na2CO3 and an outer phase of CaCl2. This seal allowed the retention of small molecules, such as dyes, as well as larger enzyme molecules, for several months. The encapsulated material could be released by dissolution of the CaCO3 with acid, upon a large dilution in water, or by applying a sufficient shear. The degree of release could be controlled since the greater the mass of CaCO3 precipitated onto the colloidosome shell, the greater the dilution or shear required to achieve release. The calcium carbonate seal protected encapsulated amylase from the detrimental effects of components in a liquid laundry detergent for several months so that, on triggered release, the enzyme retained its high activity
