Encapsulation is a powerful technique, used in a wide range of industrial applications, to protect and allow for controlled release of active ingredients. Often, polymers are used to form a shell around the active ingredient, however, due to the porous nature of a polymer network, such shells do not effectively protect sensitive active ingredients from moisture and oxygen degradation, and can not prevent diffusion of the active ingredient into favourable bulk conditions. With the micro-plastics ban and drive for more environmentally friendly materials, this project explores the ability of inorganic materials to protect small molecule/sensitive active ingredients efficiently, whilst allowing for controlled release at the desired place and time.
