Nano-Carrier Systems: Theories, Methods, and Applications is a comprehensive overview of nanomaterials fabrication, characterization, pharmaceutical application and also an exhaustive of discussion describing toxicity issues related with various existing nanoparticles. Chapter beginning with a brief introduction describing the different and diverse nanocarriers that includes Solid Lipid Nanoparticles, Metal Nanoparticles, Liposomes, Niosomes, Dendrimers, Nanocapsules, Aquasomes, Nanosuspensions, Microemulsions, Hydrogels, Nanofibers, ISCOMs, Polymeric Nanoparticles, and Polysaccharide Nanoparticles. The last section covers the emerging application in the areas of tissue engineering, imaging, which is critical to targeted delivery of the drug, as well as to evaluation of drug efficacy. This book aims to ease the superficial difficulties of fundamental designing of nano-carriers through schematic presentation, and illustration involved in formulation and evaluation of pharmaceuticals and biopharmaceuticals. The book has been prepared to introduce undergraduates to the technologies underpinning these emerging and existing products, provide a reference volume for graduate scholars seeking an introduction to the fields of pharmaceutical nanoscience and pharmaceutical nanotechnology and provide the expert with accessible information on complementary areas.
