Abstract
Methods and compounds for the measurement in vivo of oxygen in living tissue. The compounds preferably comprise a substituted porphyrin which is soluble in aqueous solution which is capable of absorbing an amount of energy and subsequently releasing the energy as phosphorescent light. In preferred embodiments, the porphyrin has an absorption band which is at a wavelength in the near infra-red window of living tissue and the phosphorescence is quenched by molecular oxygen according to the Stern-Volmer relationship.
