This book provides an overview of the cumulative work on a driving force for innovation in medicine and modern healthcare, boosting advances in therapeutics, biosensors, vaccines, and clinical systems. The work presented shows how nanoparticles have been investigated as vaccine adjuvants because they possess chemical and structural properties that improve immunogenicity as well as the use of nanotechnology in the construction of immunization systems that has developed into the field of viral nanovaccinology. The volume highlights potential areas of research, innovation, and development of finished products for future commercialization and significant research exploration through nanoparticles that prove capable of surmounting most of the barriers like toxicity issues, clearance from biological system, DNA instability, and differences in expression systems. The contributing authors review the primary literature on principles, limitations, and recent breakthroughsin nanoparticle-based antigen delivery vehicles, their use in different diseases, the major bottlenecks, and related issues. Highlighting advances in nanoparticle engineering and the understanding of nanoparticle characteristics as well as critical legacy work dome in the field of nanobiotechnology, the book is ideal for a range of researchers and students in the pure and applied sciences devoted to nanomaterials, vaccinology, and translational medicine.
