The to-date literature search on encapsulation and micro-encapsulation produces over 37000 references, with the earliest results originating back in the early 1900-th and as early as XIX century. The interest in encapsulation, seemingly non-fading since its inception, has been recently prompted by new requirements from myriad of industrial applications. In the last decade, the interest in encapsulation and micro-encapsulation has sprung anew with novel materials and technologies available for it: for example, developments in the area of polymeric microcapsules. That, in turn, ignited research in the area of release of encapsulated materials. Encapsulation evokes a great variety of not only methods, materials, techniques but also a large number of various industries and research institutions became interested in using it. Perhaps most notably, the scope of industries ranges from pharmaceutical, food, perfume to agriculture and materials. Besides drug delivery, the emphasis in this milieu is focused on more effective storage and delivery of materials. Notwithstanding, the encapsulation methods are equally important in research centers where it can be used for studying intracellular processes, exploring bio-chemical reactions in confined volumes, etc.
