A Review on Various Techniques of Microencapsulation

Abstract

The formulation of natural substances together with a biocompatible or biodegradable carrier material to form composites or encapsulates has a great relevance for pharmaceutical, cosmetic and food industries. The main objective of this article is taking a look at microencapsulation as a novel drug delivery system. Its scope extends beyond conventional microcapsules to all other small particulate systems such as self-assembling structures that involve preparative manipulation. The review covers encapsulation materials, techniques of preparation, physics of release through the capsule wall, characterization of microcapsules and the many uses to which microcapsules are put. The review of State of Art of Microencapsulation of Microcapsule Preparation Process Technology is a well established dedicated to the preparation, properties and uses of individually encapsulated novel small particles, as well as significant improvements to tried-and-tested techniques relevant to microcapsules and their use in a wide variety of industrial, engineering, pharmaceutical, biotechnology and research applications.
