This volume explores disease diagnosis and therapy in developing theranostics. The chapters in this book are divided into four parts and cover various techniques used in studying bioengineering, molecular diagnostics, in vivo imaging, and imaging-guided therapy. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, Theranostics: Methods and Protocols is a valuable tool for novice and expert clinicians, researchers, and students working in this multidisciplinary field.
