Since the first edition of Liposomes - A Practical Approach was published in 1990, liposome technology has become a highly successful and rapidly developing area of preclinical and clinical research. During the 1990's, a number of liposome-based drugs reached the market in the US and Europe and several new aspects of liposome research have been discovered. As a consequence there has been an explosion of new procedures and techniques in the field. Reflecting both the significant changes in the field and these discoveries, this new edition contains a combination of chapters from the 1st edition which have been significantly updated, and several additional chapters. Each chapter contains contributions from experts in the field, and the book as a whole encompasses all key areas of liposome technology. The first half of the text addresses a number of essential experimental protocols such as the preparation, characterization, and storage of liposomes.
