Abstract
For over a half a century now, microencapsulation has played a very important role in many industries and in the recent decades, this versatile technology has been applied to numerous biotechnology and medical processes. However, successful application in these areas requires a methodology which has the capability to produce mono-dispersed, homogenous-shaped capsules, with a narrow size distribution, using a short production time. The manufacture of capsules using vibrating technology has gained significant interest mainly due to its simplistic approach to produce homogenous microcapsules with the desired characteristics for biotechnological and medical processes. However, certain limitations still exist for this methodology, which include the inability to manufacture microcapsules at large quantities and/or using highly viscous polymers. In this review, a detailed description of the theoretical and practical aspects behind the production of different types of alginate-based microcapsules, for application in biotechnological and medical processes, using vibrating technology, is given.
