Presenting breakthrough research pertinent to scientists in a wide range of disciplines-from medicine and biotechnology to cosmetics and pharmacy-this Second Edition provides practical approaches to complex formulation problems encountered in the development of particulate delivery systems at the micro- and nano-size level. Completely revised and expanded to represent the most up-to-date studies in the field, this guide covers advances in pulsatile delivery systems, injectable microparticulate systems, and site-specific delivery systems, as well as potential therapeutic applications of nanotechnology.
