Successful delivery of biopharmaceuticals is a major challenge because their molecular properties lead to poor physical and chemical stability in the body and limited membrane permeability. Delivery technologies for biopharmaceuticals is the first single-volume reference to describe the strategies to overcome the main barriers for successful delivery of all major classes of biopharmaceuticals--peptides, proteins, nucleic acids, and vaccines. With extensive case studies showing how the science has been put into practice.
