1. A method for determining oxygen tension in a biological system, comprising the steps of introducing a physiologically acceptable paramagnetic material to a surface of the biological system, said paramagnetic material having electron paramagnetic resonance spectra responsive to the presence of oxygen, protecting the material from sources of oxygen that are outside of the biological system, and determining the oxygen tension from the electron paramagnetic resonance spectra of the material.
