conditions, which is indicative of the robustness and stability of the hybrid capsule. The examples above demonstrate the successful synthesis of a hybrid capsule by heterocoagulating organic polymer latex particles with a primary capsule. The examples also show that stability of the capsules is enhanced by having an additional layer of polymer around the micron sized capsules such as silica capsules. The results therefore show that the common drawbacks of micron sized capsules (such as capsule breakability and porosity etc.) can be addressed by embodiments of the method disclosed herein. APPLICATIONS Embodiments disclosed herein provide a method that involves applying a heterocoagulation approach and creating a polymer film to impart stability to primary capsules such as silica capsules with actives (which normally have lot of instability issues such as capsule breakability, settling or creaming in water depending on the density of the active). The inventors have surprisingly found out that desirable capsules may be produced via a simple heterocoagulation approach to obtain a film of polymer on a shell of a primary capsule such as a silica shell without using any chemical modification, notwithstanding that the primary capsule used may be considered one that is originally unstable (e.g. fragile inorganic capsules such as silica capsules). This is surprising as there was no prior knowledge or indication that such a film coating is possible on a primary capsule surface to reinforce a primary capsule shell, without breaking the micron or submicron sized primary capsule. Embodiments of the method are capable of producing hollow capsules (contrast with solid nanoparticles) that are biocompatible, degradable, environmentally benign, chemically and physically stable. For example, hybrid capsules produced by embodiments of the methods disclosed herein are
