such as silica shell. The water-based polymer latex nanoparticles may then be heterocoagulated on a primary capsule e.g. silica capsule surface and allowing polymer chains to interpenetrate to seal the pores and create a polymer shell on top of the silica hollow sphere. As such, embodiments of the methods disclosed herein are capable of blocking porous channels in primary capsules by coating polymer leading to longer and better protection of the encapsulated material. The hybrid capsules may thus be hermetically sealed unlike in the case of pure silica capsules. Embodiments of the methods disclosed herein also versatile. For example, embodiments of the methods disclosed herein are compatible with polymers having favorable film forming properties and wide-ranging polydispersity indexes (including degradable/biodegradable, bioresorbable and/or non-toxic polymers). In one particular example, embodiments of the disclosed method are capable of coating polycaprolactone latex around otherwise breakable silica capsules. Given that polycaprolactone is biodegradable, bioresorbable and non-toxic, cosmetic and even cosmeceutical applications become easy with this approach. In embodiments of the disclosed method, the polymer can be varied to generate different properties including stimuli responsive and degradable nature. Embodiments of the method disclosed herein make it possible to introduce multiple functionalities to a capsule easily which allows the method to be adapted as one that has a modular approach. This is possible as embodiments of the disclosed methods do not involve stabilization of droplets by pickering emulsion and thus allow for a variety of functionalities to be possible to be present on the capsule through the ability to use different polymers (including stimuli responsive polymers). As such, the capsules produced by embodiments of the methods disclosed herein may be customised to release their actives at certain predetermined conditions. The benefits offered by embodiments of the disclosed methods in terms of protection of the active and versatility of the release options, make the approach valuable.
