内容説明

Extending the use of nitroxides as probes into more complex systems such as viable cells and whole animals requires greater knowledge of their interactions in functioning biological systems and appropriate model systems. Nitroxide Spin Labels: Reactions in Biology and Chemistry presents information essential for research in this area. Nitroxide research offers the promise of important new ways of measuring metabolism and will be useful in the diagnosis of important disease categories such as cancer, inflammation, and ischemia.
