Proteomics is a study which takes the existence and activities of all proteins in cells as the research object for a more in-depth understanding of the laws of life activity. Since the concept of proteome was proposed in 1995, proteomics has achieved rapid development during the past decades. As a significant part of post-genomics, proteomics has strengthened its position and also become the forefront of scientific research in this century. Magnetic nanomaterials in proteomics analysis is an interdisciplinary field combining magnetic nanomaterials science and proteomics. From the current research, magnetic nanomaterials have shown great potential in complex proteomics research.This book focuses on the application of magnetic nanomaterials in the forefront of proteomics research, and describes in details the synthetic methods, properties, principles and performance of magnetic nanomaterials in various branches of proteomics, which includes digestion studies, enrichment of low abundance peptides, as well as the analysis of phosphoprotein and glycoprotein. Past 10 years' research on magnetic materials in proteomics is integrated, and then the application of magnetic nanomaterials in proteomics analysis are stated systematically.This book can serve as reference book for teaching in the major of proteomics analysis, and also can be reference book for researchers who are studying materials for proteomics.
