Nanotechnology: Molecular Speculations on Global Abundance

Product Description
Technology is becoming molecularly precise. Nanotechnology, otherwise known as molecular engineering, will soon create effective machines as small as DNA. This capacity to manipulate matter — to program matter — with atomic precision will utterly change the economic, ecological, and cultural fabric of our lives. This book, which is accessible to a broad audience while providing references to the technical literature, presents a wide range of potential applications of this new material technology. The first chapter introduces the basic concepts of molecular engineering and demonstrates that several mutually reinforcing trends in current research are leading directly into a world of surprisingly powerful molecular machines. Nine original essays on specific applications follow the introductory chapter. The first section presents applications of nanotechnology that interact directly with the molecular systems of the human body. The second presents applications that function, for the most part, outside the body. The final section details the mechanisms of a universal human-machine interface and the operation of an extremely high resolution display system.

Nanotechnologies in Food

Product Description
Recent developments in the field of nanotechnology have paved the way for lots of innovation in a number of industrial and consumer sectors, including food and food packaging. Whilst nanofood sector is a relatively new emergent, it is widely expected to grow rapidly in the future. A number of nano-sized additives and supplements for food and healthfood products, and nanotechnology derived food packaging materials, are already available in some countries, and their number is expected to increase in the coming years. Whilst such developments offer enormous benefits to the food sector, they have also raised a number of issues in relation to consumer safety, environmental impacts, and ethical, policy and regulatory aspects. Despite these rapid developments in nanotechnology applications for the food sector, only a few reports and articles are currently available that provide an account of the new developments and the current size of market for nanotechnology products and applications. These also do not provide a critical evaluation of the broader aspects of the technology, such as issues around safety of the products to consumers and the environment, and adequacy of the existing regulatory controls. This book provides a source of much needed and up-to-date information on the products and applications of nanotechnology for the food sector – for scientists, regulators, and consumers alike. It also gives an independent, balanced, and impartial view of the potential benefits as well as risks that nanotechnology applications may bring to the food sector. Whilst providing an overview of the state-of-the-art and foreseeable applications to highlight opportunities for innovation, the book also discusses areas of uncertainty in relation to public perception of the new technological developments, and potential implications for consumer safety and current regulatory controls. The book also discusses the likely public perceptions of nanotechnologies in the light of past technological developments in the food sector, and how the new technology will possibly be regulated under the existing regulatory frameworks.

Safe Nanotechnology in the Workplace

Product Description
The National Institute for Occupational Safety and Health (NIOSH) is the Federal agency responsible for conducting research and making recommendations to prevent work-related injury, illness, and death. As such, NIOSH is active in identifying critical issues related to possible health hazards of nanomaterials, protecting the safety and health of workers involved in this emerging technology, implementing a strategic plan to develop and disseminate methods for safely advancing the technology through workplace controls and safe handling procedures, and investigating the possible applications of nanotechnology to solve workplace safety and health issues. Because of their small size and large surface area, engineered nanoparticles may have chemical, physical, and biological properties distinctly different from larger particles of similar chemical composition. Those properties may include the ability to reach the gas exchange regions of the lung, travel from the lung throughout the body, penetrate dermal barriers, cross cell membranes, and interact at the molecular level. NIOSH is investigating all of these properties, as it would with any new technology or material in the workplace, to provide the necessary guidance to ensure a safe and healthy workplace.

Nanotechnology in Food Products: Workshop Summary

Book Description
In the food industry, scientists are exploring the potential of nanotechnology to enhance the flavor and other sensory characteristics of foods, introduce antibacterial nanostructures into food packaging and encapsulate and deliver nutrients directly into targeted tissues, among other applications.

However, as with any new technology, along with the benefits, there is the potential for unanticipated adverse effects. There is still a great deal to learn about any health outcomes related to introducing nanosized materials into foods and food packaging materials. Developing nanotechnology into a safe, effective tool for use in food science and technology will require addressing these and other questions. Assuring consumer confidence will be equally important to the success of this new emerging technology.

The Institute of Medicine held a one-day workshop, summarized in this volume, to further explore the use of nanotechnology in food. Specifically, the workshop was organized around three primary topic areas: (1) the application of nanotechnology to food products; (2) the safety and efficacy of nanomaterials in food products; and (3) educating and informing consumers about the applications of nanotechnology to food products.
