Nanotoxicity

Nanomaterials - substances smaller than 100 nanometers in size - have been added in recent years to an increasing numbers of consumer products used in day-to-day life; in food packaging, medical devices, pharmaceuticals, cosmetics, odor-resistant textiles and household appliances. The extensive application of nanomaterials in a wide range of products for human use poses a potential for toxicity risk to human health and the environment. Such adverse effects of nanomaterials on human health have triggered the development of a new scientific discipline known as “nanotoxicity” – the study of the toxicity of nanomaterials. Nanotoxicity: From in vivo and in vitro Models to Health Risks provides up-to-date state-of-the-art information presented by recognized experts in this emerging new field in toxicology. It discusses the safety evaluation of nanomaterials in foods, drugs, medical devices, cosmetics and other regulated products and its use in risk analysis for potential regulatory use. Topics covered include: biomarkers for nanotoxicity assessment nanotoxicity assessment by gene expression analysis in vivo and in vitro models for nanotoxicity testing mechanisms of nanotoxicity pharmakokinetics of nanomaterials nanotoxicity of foods including food processing, food packaging and food safety nanotoxicity of drugs including drug development and drug delivery nanotoxicity of cosmetics and consumer products health and environmental impact of nanotoxicity safety evaluation of nanomaterials regulatory impact of nanomaterials Nanotoxicity: From in vivo and in vitro Models to Health Risks is a valuable authoritative source of information for readers from a wide range of disciplines such as toxicology, pharmacology, drug toxicity and food and environmental sciences. The book will be useful to the research community in academia, industry, hospitals and government, as well as to government regulators and risk assessors of foods, drugs and environmental and agricultural products.

Nanotoxicity: Prevention, and Antibacterial Applications of Nanomaterials focuses on the fundamental concepts for cytotoxicity and genotoxicity of nanomaterials. It sheds more light on the underlying phenomena and fundamental mechanisms through which nanomaterials interact with organisms and physiological media. The book provides good guidance for toxic prevention methods and management in the manufacture/application/disposal. The book also discusses the potential applications of nanomaterials-based antibiotics. The potential toxic effects of nanomaterials result not only from the type of base materials, but also from their size/ ligands/surface chemical modifications. This book discusses why different classes of nanomaterials display toxic properties, and what can be done to mitigate this toxicity. It also explores how nanomaterials are being used as antimicrobial agents, being used to purify air and water, and counteract a range of infectious diseases. This is an important reference for materials scientists, environmental scientists and biomedical scientists, who are seeking to gain a greater understanding of how nanomaterials can be used to combat toxic agents, and how the toxicity of nanomaterials themselves can best be mitigated. Explains the underlying phenomena and fundamental mechanisms through which nanomaterials interact with organisms and physiological media Outlines major methods for mitigating and prevention of nanotoxicity Discusses the applications of nanomaterials-based antibiotics

This book provides a comprehensive overview of the fundamentals of nanotoxicity modeling and its implications for the development of novel nanomedicines.

This book focuses on the toxicity of engineered nanomaterials (ENMs) and their underlying physicochemical, cellular, physiological, and molecular mechanisms. Further, it covers ENMs’ translocation and their targeted organ toxicology, and discusses chemical and pharmacological strategies used to combat nanotoxicity. Engineered nanomaterials (ENMs) are defined as materials with one or more dimensions of less than 100 nm, and have shown considerable promise in several areas of development. At the same time, the potential toxicity of ENMs for human health and environmental organisms is increasingly attracting attention. In addition to the typical properties of model animals, Caenorhabditis elegans is extremely sensitive to environmental toxicants, which makes it the ideal in vivo assay system for toxicological studies. C. elegans has been widely used in toxicity assessment and toxicological studies of environmental toxicants and stresses. This book provides a comprehensive summary of nanotoxicology research on C. elegans.

The field of nanomedicine has risen quickly due to the increasing number of designer-made nanomaterials.

As the application of nanotechnology in the myriad disciplines of science and engineering--from agriculture, pharmaceuticals, material science, and biotechnology to sensors, electronics, and mechanical and electrical engineering--brings benefits it also can produce serious threats to human health and the environment that must be evaluated. The unique properties of nanomaterials make them different from their bulk counterparts. In addition to such unique properties, the nanometric size of nanomaterials can invite some detrimental effects on the health and well-being of living organisms and the environment. Thus, it is important to distinguish nanomaterials with such ill effects from nanomaterials with no or minimum toxicity. Nanotoxicology: Toxicity Evaluation, Risk Assessment and Management covers issues such as the basic principles of nanotoxicity, methods used for nanotoxicity evaluation, risk assessment and its management for nanomaterial toxicity with a focus on current trends, limitations, challenges, and future directions of nanotoxicity evaluation. Various experts from different countries discuss these issues in detail in this book. This will be helpful to researchers, educators, and students who are interested in research opportunities for avoiding the environmental and health hazards of nanomaterials. This book will also be useful for industrial practitioners, policy makers, and other professionals in the fields of toxicology, medicine, pharmacology, food, drugs, and other regulatory sciences.
