Nanomedicine offers a range of multi-interdisciplinary approaches and brings together the field of chemistry, pharmaceutical science, biology, and clinical medicines by focusing on design and preparation of biodegradable or non-biodegradable biomaterials for their biological, medical, and pharmaceutical applications. Nanomaterials in Advanced Medicine reviews the concepts and applications of the combination of the technology of biology and engineering that are emerging as an integral aspect of today?s advanced medicine. Nanomedicine provides the technology for imaging, cancer treatment, medical tools, bone treatment, drug delivery, diagnostic tests, drug development, angiogenesis and aims to exploit the improved and often novel physical, chemical, and biological properties of materials at the nanometer scale.
Designed to provide a broad survey of the field, Nanomaterials in Advanced Medicine is divided into three main sections: Nanophysics, Nanochemistry, and Nanomedicine. Each chapter describes in detail the most current and valuable methods available and contains numerous references to the primary literature. This important book:
-Offers a field guide for biologists and physicians who want to explore the fascinating world of nanotechnology
-Contains a comprehensive review of the topic from a noted expert in the field
-Includes an introduction to nanotechnology and explores the synthesis, structure and properties of various types of nanobiomaterials
-Bridges the gap between various aspects of nanomaterials? development technology and their applications
Written for pharmaceutical chemists, biotechnologists, life scientists, materials scientists, polymer chemists, and biochemists, Nanomaterials in Advanced Medicine provides a must-have guide to the fundamental concepts and current applications of nanomaterials in the medical field.
