A mixture of two polymers, or one polymer and a salt, in an aqueous medium separates into two phases: this phenomenon is useful in biotechn- ogy for product separations. Separation of biological molecules and particles in these aqueous two-phase systems (ATPS) was initiated over 40 years ago by P.-Å. Albertsson, and later proved to be of immense utility in biochemical and cell biological research. A boost in the application of ATPS was seen when problems of separations in biotechnology processes were encountered. Its simplicity, biocompatibility, and amenability to easy scaleup operations make the use of ATPS very attractive for large-scale bioseparations. Despite the advantages ATPS enjoys over other separation techniques, the application of two-phase systems has for a long time been confined to selected labora- ries. Recent years have, however, shown a trend in which increasing numbers of researchers employ two-phase partitioning techniques in both basic and applied research.

This volume is a valuable reference work for the student and the practising engineer in the chemical, pharmaceutical, minerals, food, plastics, paper and metallurgical industries. The second edition of this successful text has been thoroughly rewritten and updated. Based on the long running post-experience course produced by the University of Bradford, in association with the Institution of Chemical Engineers, it covers all aspects of mixing, from fundamentals through to design procedures in single and multi-phase systems. Experts from both industry and academia have contributed to this work giving both a theoretical practical approach. It covers dry and wet powders, single and two-phase liquids, solid/liquid and gas/liquid systems. The range of mixers available for such diverse duties is dealt with, including tumbler mixers for powders, mechanically agitated vessels, in-line continuous mixers and jet mixers. Coverage is given of the range of mixing objectives, varying from achieving product uniformity to obtaining optimum conditions for mass transfer and chemical reactions.

Engineering of Biomaterials for Drug Delivery Systems: Beyond Polyethylene Glycol examines the combined issues of PEGylation and viable biomaterials as alternatives. With a strong focus on polymeric biomaterials, the book first reviews the major issues associated with PEGylation and its use in vivo. Chapters then focus on alternative polymer systems for drug delivery systems. Finally, nanoparticles and future perspectives are examined. This book is a valuable resource for scientists and researchers in biomaterials, pharmaceuticals and nanotechnology, and all those who wish to broaden their knowledge in this field. - Provides a self-contained work for the field of biomaterials for drug delivery - Summarizes the current knowledge on PEGylation and strategies for bypassing it - Presents research on an important, though under-represented issue in biomaterials - Written by a world-class team of research scientists, engineers and clinicians
