Dendrimers are repeatedly branched and roughly spherical large molecules. They can be used in various medical applications, such as anticancer polymeric nanomedicines and nanocarriers, gene carriers and vectors in gene delivery, contrast agents for molecular imaging and vaccines against infectious diseases and cancer. The highly branched, multivalent nature and molecular architecture of dendrimers make them ideal tools for a variety of tissue engineering applications. This book describes different categories of dendrimers, their biomedical and physico-chemical applications as well as convergent and divergent syntheses, click chemistry and ligation strategies. It is a rich source of information for researchers in biochemistry and pharmacology working on drug development as well as for organic chemists who are engaged in synthesis of dendrimers.
