Abstract
An oxygen sensitive probe comprises a monofunctional derivative of an oxygen-sensitive photoluminescent dye covalently attached to a water soluble and/or hydrophilic macromolecular carrier. The probe may be a chemical conjugate of a monofunctional phosphorescent porphyrin dye and a poly(ethyleneglycol), polypeptide or polysaccharide.
