This book reviews the application of nanosensors in food and agriculture. Nanotechnology has the potential to become transformative technology that will impact almost all sectors. Tools like nanosensors, which detect specific molecular interactions, can be used for on-site, in-situ and online measurements of various parameters in clinical diagnostics, environmental and food monitoring, and quality control. Due to their unprecedented performance and sensitivity, nanobiosensors are gaining importance in precision farming. The book examines the use of nanobiosensors in the monitoring of food additives, toxins and mycotoxins, microbial contamination, food allergens, nutritional constituents, pesticides, environmental parameters, plant diseases and genetically modified organisms. It also discusses the role of biosensors in increasing crop productivity in sustainable agriculture, and nanosensor-based smart delivery systems to optimize the use of natural resources such as water, nutrients and agrochemicals in precision farming.

The present book is devoted to all aspects of biosensing in a very broad definition, including, but not limited to, biomolecular composition used in biosensors (e.g., biocatalytic enzymes, DNAzymes, abiotic nanospecies with biocatalytic features, bioreceptors, DNA/RNA, aptasensors, etc.), physical signal transduction mechanisms (e.g., electrochemical, optical, magnetic, etc.), engineering of different biosensing platforms, operation of biosensors in vitro and in vivo (implantable or wearable devices), self-powered biosensors, etc. The biosensors can be represented with analogue devices measuring concentrations of analytes and binary devices operating in the YES/NO format, possibly with logical processing of input signals. Furthermore, the book is aimed at attracting young scientists and introducing them to the field, while providing newcomers with an enormous collection of literature references.

We have come to know that our ability to survive and grow as a nation to a very large degree depends upon our scientific progress. Moreover, it is not enough simply to keep abreast of the rest of the world in scientific matters. 1 We must maintain our leadership. President Harry Truman spoke those words in 1950, in the aftermath of World War II and in the midst of the Cold War. Indeed, the scientific and engineering leadership of the United States and its allies in the twentieth century played key roles in the successful outcomes of both World War II and the Cold War, sparing the world the twin horrors of fascism and totalitarian communism, and fueling the economic prosperity that followed. Today, as the United States and its allies once again find themselves at war, President Truman’s words ring as true as they did a half-century ago. The goal set out in the Truman Administration of maintaining leadership in science has remained the policy of the U.S. Government to this day: Dr. John Marburger, the Director of the Office of Science and Technology (OSTP) in the Executive Office of the President made remarks to that effect during his confirmation hearings in October 2 2001.

Biosensors for Sustainable Food - New Opportunities and Technical Challenges addresses the challenges associated with sustaining the globally increasing demand for food that has been forecast for the next centuries and the immediate need for the food production system to adopt sustainable practices to protect the environment and human health. It provides a comprehensive overview of established, cutting-edge, and future trends in biosensor technology and its application in the agrifood sector. In particular, different biosensing advances are covered, outlining the newest research efforts in the cross-disciplines of chemistry, biology, and materials science with biosensing research, in order to develop novel detection principles, sensing mechanisms, and device engineering methods. Food production and consumption have a strong impact on the environment in terms of greenhouse gas emissions, water, and soil contamination, the reduction of arable land, water consumption, and many other factors, which in turn, negatively affect human health. These issues have consequences for economic development, too. To address these challenges, it is necessary for scientists with different expertise, policymakers, and economists work together to develop new smart technologies and introduce them to the market, along with adequate regulations. In this regard, a sustainable food production system can be thought of as a chain of procedures with a low impact on the environment that guarantees a secured supply of healthier and fortified food while supporting economic growth. - Presents an interdisciplinary approach to biosensor technology - Profiles recent advances in synthetic biology, new material design (biohybrids), nanotechnology, micro/nanofluidics, and information technology - Aims to facilitate the transfer of agrifood biosensor technology from the laboratory to the market
