"The book …presents the first comprehensive reference concerned exclusively with this topic. The book provides an easy access to the subject both for those who are just starting to work in the field and for experience professionals. It affords a broad survey of hydrogel synthesis, degradation, and use for drugdelivery."-Benedikt T. Haag, Department of Chemistry, Virginia Commonwealth University, in Journal of Bioactive and Compatible Polymers"This book is an excellent addition to the literature of controlled delivery of bioactive materials. It is well written, edited, and referenced. I would strongly recommend this book to …those in the biotechnology and pharmaceutical industries."-Tarun K.Mandal,Assistant Professor of Pharmaceutics, Xavier University of Louisiana, in BioPharm
