Book Preface

Applications of microelectromechanical systems (MEMS) and microfabrication have spread to different fields of engineering and science in recent years. Perhaps the most exciting development in the application of MEMS technology has occurred in the biological and biomedical areas. In addition to key fluidic components, such as microvalves, pumps, and all kinds of novel sensors that can be used for biological and biomedical analysis and measurements, many other types of so-called micro total analysis systems (TAS) have been developed. The advantages of such systems are that microvolumes of biological or biomedical samples can be delivered and processed for testing and analysis in an integrated fashion, thereby dramatically reducing the required human involvement in many steps of sample handling and processing. This helps to reduce the overall cost of measurement and time, while improving the sensitivity in most cases.

Many books have been published on these subjects in recent years, but most of them have focused primarily on various fabrication technologies with a few application areas highlighted. Unfortunately, in this burgeoning area, only a couple of books have been directed specifically toward biomedical MEMS. As MEMS applications spread to all corners of science and engineering, more and more universities and colleges are offering courses in the bio-MEMS area. In comparison with other MEMS areas, which typically involve different engineering disciplines, such as the mechanical, electrical, and optical fields, the development of bio-MEMS devices and systems involves a truly interdisciplinary integration of basic sciences, medical sciences, and engineering. This is the primary reason bio-MEMS is still in the earliest stages of development in comparison with electrical and mechanical sensing devices and systems. Due to the complexity and interdisciplinary nature of bio-MEMS, it is critical to include a diverse range of expertise in the composition of a book that attempts to cover the bio-MEMS area from both a fabrication and application point of view. This is the reason we have assembled a large group of leading researchers actively working in basic science, engineering, and biomedical areas to contribute to this book. Bio- MEMS: Technologies and Applications is divided into three sections:

1. Basic Bio-MEMS Fabrication Technologies
2. Microfluidic Devices and Components for Bio-MEMS
3. Sensing Technologies and Bio-MEMS Applications

The book targets audiences in the basic sciences and engineering, both industrial engineers and academic researchers. Efforts have been made to ensure that while enough topics on the cutting edge of bio-MEMS research are covered, the book is still easy to read. In addition to structurally organizing the book from basic materials to advanced topics, we have made sure that each chapter and subject area are covered beginning with basic principles and fundamentals. Because of the shortage of suitable textbooks in this area, this collection is designed to be reasonable for graduate education as well as working application engineers who are interested in getting into this exciting new field.
