Nanosized particles explored for therapeutics and diagnosis related research areas need updated latest information for the budding researcher as well as academicians. Nanomedicine, Nanotheranostics and Nanobiotechnology has been a contemporary technological tool for diverse biomedical, pharmaceutical and diagnostic solutions. The present book is divided into two sections. Section A (16 chapters) is dedicated to the exclusive book chapters related to Nanomedicine area such as History, regulatory, scale-up, regulatory toxicology aspects of nanomedicine. Additionally, this section include chapters focusing on application domain of nanomedicine for targeted cancer therapy, rheumatoid arthritis management, psoriasis, ocular delivery, topical applications, oral bioavailability enhancement and pulmonary delivery etc. Section B (10 chapters) comprised of chapters in the area of nanotheranostics and applications of nanobiotechnology. In brief, latest topics such as gold nanoparticles in diagnostics and therapy, nanoparticles for siRNA delivery, carbon nanotubes for gene delivery, nanoparticles for vaccine delivery, nanobiotechnology in cell-based nanomedicines, nanotechnology in regenerative medicine and nanocarriers in delivery of proteins and peptides are complied. Key features: • A total of 26 emerging topics are covered in the book on the cutting edge research areas at the multi-disciplinary level. • The chapters are focusing from fundamentals to the applications part making it attractive for beginner as well as the experts. • The chapters are written by the one of the well-known experts of the field in simple scientific style with figures, scheme and illustrations. Dr. Rishi Paliwal and Dr. Shivani Rai Paliwal, Editors of the book, both are domain experts who are continuously exploring nantechnological principles for diverse biomedical and pharmaceutical applications since two decades. Being established nanomedicine scientist, the book has been edited well with profound knowledge base.
