This detailed second edition volume expands upon the prior edition by addressing newly emerged technologies as well as improved existing protocols in nucleic acid delivery via nanotechnology. The book addresses topics ranging from chemical synthesis of macromolecules and bioconjugates, novel and established nanoformulations, characterization of these nanoformulations for biophysical, biological and toxicological aspects, and also protocols dealing with application and imaging of such carrier systems in vivo. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective chapters, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
