Featuring contributions from renowned subject-matter experts, this book provides a better understanding of how inhaled nanoparticles behave in the lungs and body. It describes the sequence of events that nanoparticles encounter in the lungs when moving from the air into the bloodstream, as well as addresses practical considerations for drug delivery to the respiratory tract, drug and gene delivery in the lungs, and bio-nanocapsules. In addition, the book explores issues such as dosimetry for in vitro nanotoxicology and the potential for nose-to-brain delivery of drugs.
