Biomedical Nanozymes

This​ book reviews the latest advances and biomedical applications of nanozymes, which are artificial nanomaterials exhibiting enzymatic properties similar to natural enzymes, but with less limitations than natural enzymes. Nanozymes display advantages such as facile synthesis, easy surface modification, improved stability, higher catalytic power, and target-specific binding. Nanozymes containing metals, metal oxides, carbon, and metal sulfide are actually used for cancer therapy, biomolecules sensing, bioimaging, disease diagnostics and diabetes management. The book discloses underlying mechanisms, concepts, recent trends, constraints, and prospects for nanomedicine using nanozymes.

This book aims to summarize the latest research progress of biomedical nanozymes in diagnostic and therapeutic related fields. In terms of diagnostics, it will cover in vitro diagnostics, live analysis, and some emerging bioanalysis. In terms of therapeutics, it will introduce antioxidant therapy, peroxidation therapy and emerging therapy respectively. Furthermore, the research results previously scattered in many journals and conferences worldwide are methodically edited and presented in a unified form. Based on the new ideas and developments presented in this book, it will be of interest to readers from different areas, such as chemistry, materials, nanoscience and nanotechnology, biomedical and clinical studies, etc.

This book describes the fundamental concepts, the latest developments and the outlook of the field of nanozymes (i.e., the catalytic nanomaterials with enzymatic characteristics). As one of today’s most exciting fields, nanozyme research lies at the interface of chemistry, biology, materials science and nanotechnology. Each of the book’s six chapters explores advances in nanozymes. Following an introduction to the rise of nanozymes research in the course of research on natural enzymes and artificial enzymes in Chapter 1, Chapters 2 through 5 discuss different nanomaterials used to mimic various natural enzymes, from carbon-based and metal-based nanomaterials to metal oxide-based nanomaterials and other nanomaterials. In each of these chapters, the nanomaterials’ enzyme mimetic activities, catalytic mechanisms and key applications are covered. In closing, Chapter 6 addresses the current challenges and outlines further directions for nanozymes. Presenting extensive information on nanozymes and supplemented with a wealth of color illustrations and tables, the book offers an ideal guide for readers from disparate areas, including analytical chemistry, materials science, nanoscience and nanotechnology, biomedical and clinical engineering, environmental science and engineering, green chemistry, and novel catalysis.

This book presents the state-of-the-art advances and applications of nanozymes, the recently developing branch of enzymology that synthesizes and uses nanomaterials that mimic the function of traditional enzymes. During the past decade, the study of nanozymes has grown rapidly. Several new nanomaterials that exhibit enzymatic actions have been identified, along with new applications for their practical use. This book draws upon the work of experts from around the world and provides an in-depth analysis and cutting-edge overview of nanozymes, with an eye toward their present and future applications. Chapters are arranged in a logical order to provide physio-chemical characterization of nanozyme and basic mechanisms of their enzymatic actions. Focusing on current limitations of nanozymes and their reaction kinetics, the book presents a comprehensive discourse on nanozyme engineering that includes possible surface modifications to enhance nanozyme effectiveness. It also focuses on traditional and novel nanozyme applications, such as biosensing, drug delivery, and disease therapy, as well as their use as antibacterials. An important addition in this book is the summary of emerging literature on nanozyme toxicology. This book is intended as a ready reference for advanced undergraduate and graduate students doing research in nanotechnology; materials science; chemistry; and chemical, biological, biomedical, and food engineering. Research and development scientists, engineers, and technologists working in the chemical and biological/biomedical industries will gain much from the materials in this book for their industry practice.

This book introduces the new concept of “nanozyme”, which refers to nanomaterials with intrinsic enzymatic activity, rather than nanomaterials with biological enzymes incorporated on the surface. The book presents the cutting-edge advances in nanozyme, with emphasis on state-of-the-art applications in many important fields, such as in the biomedical fields and for environmental protection. The nanozyme is a totally new type of artificial enzyme and exhibits huge advantages over natural enzymes, including greater stability, low cost, versatility, simplicity, and suitability for industry. It is of interest to university researchers, R&D engineers, as well as graduate students in nanoscience and technology, and biology wishing to learn the core principles, methods, and the corresponding applications of “nanozyme”.

This book reviews the latest developments and applications of nanozymes in environmental science. Protection of the environment is essential because pollution has become a global problem with many adverse effects on life and ecosystems. For that, remediation strategies and techniques have been designed, yet they are limited. Here, the recent development of nanotechnology opens a new vista for environmental remediation. In particular, nanomaterials displaying enzyme-like activities, named ‘nanozymes’, appear very promising for environmental monitoring, contaminant detection, microbial management, and degradation of organic pollutants. Nanomaterials including metallic, metal oxides and carbon-based nanoparticles with nanozymes activities have been synthesized. These nanozymes have similar activities as natural peroxidase, oxidase, superoxide dismutase and catalase enzymes. Nanozymes have several advantages, yet they suffer from several limitations such as low catalytic efficiency, less substrate selectivity, biocompatibility, and lack of engineering of the active sites.
