Biosensing

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.

This book presents tools and techniques for the development of miniature biosensors and their applications. The initial chapters discuss the advancements in the development of the transduction techniques, including optical, electrochemical, and piezoelectric, which are used for miniaturized biosensors. The book also reviews several technologies, such as nanotechnology, nanobiotechnology, immune-technology, DNA-technology, micro-manufacturing technology, electronic-circuit technology to increase the miniaturization and sensitivity of the biosensor platform. Subsequently, the chapters illustrate the applications of miniaturized biosensing systems in point-of-care monitoring of treatment and disease progression, environmental monitoring, food control, drug discovery, forensics, and biomedical research. Towards the end, the book discusses the advanced applications of biosensors in water quality monitoring, especially on-line detection systems and on-site detection of pesticides, heavy metals and bacteria in water. This book is an invaluable source for scientists working in biochemical engineering, bioengineering, and biomedical engineering in academia and industry.
