This book comprehensively reviews the history of nanotechnology, and describes the physiochemical properties of various nanoparticles and their biomedical applications.                  Covering the biotoxicity of nanoparticles, their bio-distribution and release kinetics, and their role in diagnosis, pre-clinical drug discovery and disease prevention, it also examines the application of nanoscaffolds in tissue engineering and as cell culture templates. Further, the book discusses several fabrication methodologies for regenerative medicine, and explores nanotechnology-based stem cell therapeutics, including stem cell transfection, stem cell delivery, and stem cell expansion for promoting tissue regeneration. Lastly, it addresses the use of DNA barcoding technology from nanosamples for the detection, identification and validation of emerging pathogens, biodiversity and ancient remnants of living specimens, and highlights various strategies for the plant-mediated synthesis of nanoparticles. Given its scope, it is a valuable reference resource for graduate students and researchers interested in understanding the diverse range of biomedical applications of nanoparticles.
