This book describes measurement methods in modern biology. While many books on biological instrumentation cover only high end instrumentation, this book also encompasses measurements in the growing fields of molecular biology and biotechnology. As a first course in bioinstrumentation for undergraduate biomedical engineers, this book describes measurement methods used in the growing fields of cell engineering, tissue engineering, and biomaterials. It will also serve as a text for medical and biological personnel who wish to learn measurement techniques. It is very useful for graduate, post graduate, engineering students and research scholars.
