<p>Methods and compounds for the measurement in vivo of oxygen in living tissue. The compounds preferably comprise a chromophore which is capable of absorbing an amount of energy and subsequently releasing the energy as phosphorescent light. In preferred embodiments, the chromophore has an absorption band which is at a wavelength in the near infrared window of living tissue and the phosphorescence is quenched by molecular oxygen according to the Stern-Volmer relationship.</p> |
