This book is the first book in English on natechlogy and namaterials integrating with enzymatic systems, with a focus on naparticles and biological applications. It covers comprehensively the relevant topics to understand the development of enzyme naparticles as it relates to the complicated structures of enzyme naparticles and their functionalization and immobilization on to various supports. The preparation of enzyme naparticles, their kinetic properties and applications after immobilization of the immobilized enzyme naparticles is described. The use of colour images in all formats of the book will improve the understanding of the topics covered. The book offers an integration of Enzymology and Natechlogy and provides the latest information on preparation of enzyme naparticles, their characterization, their functionalization and immobilization on to various supports and thereafter their kinetic properties and applications in various industries with special reference to Biosensor Techlogy.
