The quantitative measurement of biotics and xenobiotics in biological systems falls under the discipline of bioanalytical chemistry. This is important for the purposes of pharmacokinetics, bioequivalence, exposure-response and toxicokinetics. It is also crucial for forensic investigations, anti-doping testing and for the analysis of drugs with an influence on the environment. Some of the techniques used in bioanalytical studies are chromatographic methods, mass spectrometry, nuclear magnetic resonance, electrophoresis, etc. The topics included in this book on bioanalytical chemistry are of the utmost significance and bound to provide incredible insights to readers. It includes some of the vital pieces of work being conducted across the world, on various topics related to bioanalysis. This book aims to serve as a resource guide for students and experts alike and contribute to the growth of the discipline.
