Biomedical Applications Of Microencapsulation

Published in 1984: For this volume the publishers at CRC Press have chosen to present information on just one important area, namely the biomedical field, where much progress in the application of microencapsulation has been made in recent years.

Nano- or micro-encapsulation is used in many different fields and industries, including pharmaceuticals, cosmetics, food, and agrochemicals. It offers advantages for various applications, especially drug delivery. Nano-encapsulation can help extend and control the release of drugs as well as increase drug bioavailability and efficacy. It improves the precision of targeted drug delivery and allows for fabricating nano-encapsulated drugs for diagnostic and theranaostic applications. This book covers recent advances in fabricating nano-/micro-capsules using natural carriers for therapeutic and diagnostic drug delivery applications as well as rheology and formulations of micro-emulsions for diverse applications. This book is essential for scientists and researchers with diverse backgrounds in chemistry, engineering, material sciences, pharmaceuticals, and drug delivery.

The field of encapsulation, especially microencapsulation, is a rapidly growing area of research and product development. Applications of Encapsulation and Controlled Release offers a broad perspective on a variety of applications and processes, including, up-to-date research, figures, tables, illustrations, and references. Written at a level comprehensible to non-experts, it is a rich source of technical information and current practices in research and industry.

of McGill University of Montreal, Canada, who talks about artifi cial cells prepared from semipermeable microcapsules. Also illustrative of this method is a contribution on microencapsulated pesticides by C. B. Desavigny and E. E. Ivy of Pennwalt Corporation. Another method of polymerization in situ is micro encapsulation by vapor deposition, the subject of W. M. Jayne of Union Carbide Corporation. The more mechanical methods of microencapsulation are represented by two techniques, one involving a fluidized bed the other involving mainly a centrifugal method. The fluidized bed method is covered in a paper by H. Hall and T. M. Hinkes of the Wisconsin Alumini Research Foundation. The centrifugal and other related methods are treated by Mr. J. E. Goodwin and Mr. Sommerville of the Southwest Research Institute of San Antoni~ Texas. Dr. G. Baxter of Moore Business Forms, studied capsules made by mechanical methods as well as by chemical methods. Mr. Russell G. Arnold of the Bureau of Veteranary Medicine of the Food and Drug Administration draws our attention to the procedures to be used for securing approval of a new animal drug application for the marketing of microencapsulated products. And last but not least, we have a contribution by Mr. G. O. Fanger on "Micro encapsulation a Brief History and Introduction, whose title speaks for itself.

This volume provides a unique forum to review cell microencapsulation in a broad sense by exploring various cell types that have been encapsulated for different purposes, different approaches and devices used for microencapsulation, the biomaterials used in cell microencapsulation, the challenges to the technology, and the current status of its application in different clinical situations. This book is divided in five sections: Section I is an introductory part that discusses historical developments of the technology and its current challenges, as well as the various applications of cell microencapsulation; Section II discusses the main approaches and devices currently used in cell microencapsulation; Section III presents an overview of the various polymeric materials currently in use for cell microencapsulation and the enabling technologies to either monitor or enhance encapsulated cell function; Section IV gives specific examples of the methods used to encapsulate various cell types; and Section V provides an overview of the different clinical situations in which cell microencapsulation has been applied. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and practical, Cell Microencapsulation: Methods and Protocols is a valuable reference for researchers, engineers, clinicians, and other healthcare professionals, as well as food technologists who will find detailed descriptions of methods for the microencapsulation of specific cell types and their current of potential clinical and industrial applications. This volume also includes detailed information about the design and manufacture of different devices including large-scale production devices for use in cell microencapsulation.

This book is intended to provide an overview and review of the latest developments in microencapsulation processes and technologies for various fields of applications. The general theme and purpose are to provide the reader with a current and general overview of the existing microencapsulation systems and to emphasize various methods of preparation, characterization, evaluation, and potential applications in various fields such as medicine, food, agricultural, and composites. The book targets readers, including researchers in materials science processing and/or formulation and microencapsulation science, engineers in the area of microcapsule development, and students in colleges and universities.
