Body-on-a-Chip: Essentials and Applications provides the reader high-quality information, in a single resource, that is necessary to explore the use of BOC systems from design and development to testing and personalized medicine, to medical research and diagnostics. BOC systems can recapitulate native tissue/ organ architecture, diffusion kinetics of drugs physiological flow conditions etc., similar to what would happen in the body, they are particularly powerful in predicting human efficacy prior to clinical testing of a drug, determining potential toxicity, or in clinical studies to test underlying mechanisms or action or adverse effects. With recent advancements in high-throughput analysis systems and artificial intelligence, it has also become possible to screen several drugs at a time.
