Nanomedicine can take advantage of the recent developments in nanobiotechnology research for the creation of platforms with superior drug carrier capabilities, selective responsiveness to the environment, unique contrast enhancement profiles, and improved accumulation at the disease site. This book provides a broad glimpse of how various dendritic nanomaterials have been designed and used as efficient tools for nanomedicine. It comprises a pedagogic introduction to dendrimers and hyperbranched systems and their classical and accelerated syntheses through cutting-edge methodologies. The chapters on dendronized magnetic nanoparticles as theranostics, dendrimers in theory (molecular simulations), siRNA delivery with dendrimers, and dendrimers for image-guided therapy, combined with chapters focused on specific types of dendrimers or hyperbranched structures, detail the cutting-edge research in nanomedicine. Finally, a detailed chapter on issues related to the pharmacokinetics and biodistribution of dendrimers helps choose the right structures for successful transfer from bench to bedside. This book will appeal to those involved in nanobiotechnology, macromolecular science, cancer therapy, tissue repair, and siRNA delivery research.
