A polymersome-stabilized Pickering emulsion was prepared and applied in a biphasic enzymatic reaction. This type of Pickering emulsion was stabilized by fully packed crosslinked polymersomes at the water/oil interface. CalB, as a model enzyme (red ribbon structure), was loaded either in the water phase or in the lumen of the polymersomes of the Pickering emulsion (see picture), which highly enhanced its catalytic performance and recyclability.
