This Ebook describes the applicability of diverse natural and synthetic biopolymers and their blends in drugs, vaccines and gene delivery. It would serve as a concise body of information on biopolymers for researchers, industries and students of pharmaceutical, chemical, engineering and biomedical sciences. Practical and theoretical concepts are presented in depth. Examples of yet untapped indigenous African polymers with drug delivery potentials are highlighted. Many natural biopolymers with excellent drug delivery properties have not been appropriately exploited because there is very concise body of information that would demonstrate their potential. This Ebook should prove to be an important resource to researchers in the field.
