Microfluidic technology is revolutionising a number of scientific fields, including chemistry, biology, diagnostics, and engineering. The ability to manipulate fluids and objects within networks of micrometre-scale channels allows reductions in processing and analysis times, reagent and sample consumption, and waste production, whilst allowing fine control and monitoring of chemical or biological processes. The integration of multiple components and processes enable "lab-on-a-chip" devices and "micro total analysis systems" that have applications ranging from analytical chemistry, organic synthesis, and clinical diagnostics to cell biology and tissue engineering. This concise, easy-to-read book is perfectly suited for instructing newcomers on the most relevant and important aspects of this exciting and dynamic field, particularly undergraduate and postgraduate students embarking on new studies, or for those simply interested in learning about this widely applicable technology. Written by a team with more than 20 years of experience in microfluidics research and teaching, the book covers a range of topics and techniques including fundamentals (e.g. scaling laws and flow effects), microfabrication and materials, standard operations (e.g. flow control, detection methods) and applications. Furthermore, it includes questions and answers that provide for the needs of students and teachers in the area.
