"HIV prevention requires a multidisciplinary approach, even when focusing on a particular biomedical intervention such as anti-HIV microbicides. This book offers a comprehensive, integrative, and balanced overview on various aspects of microbicides, including mechanisms of transmission, drug development, and clinical and regulatory aspects, with a special emphasis on formulation. It is therefore equally useful for specialized basic, pharmacological, clinical, and biotechnological scientists and will hopefully stimulate future interdisciplinary research for prevention."—Prof. Guido Vanham, Virology Unit, Institute of Tropical Medicine, Antwerp, Belgium"This treatise offers an insightful analysis on the opportunities that drug delivery technologies can afford in HIV microbicide development. It provides first-of-its-kind comprehensive overview of the challenges in microbicide delivery as well as opportunities to develop novel formulations such as polymeric implants, stimuli-responsive nanotechnology, and strategies to alter the microbiome. It also addresses the issues of socioeconomics, compliance, and regulatory oversight in the development of novel microbicides."—Prof. Mansoor M.
