摘要: A method for in vivo measurement of oxygen concentration levels animal bodily fluids or tissues comprises administering a biocompatible fluoroescent probe sensitive to quenching and having known unquenched fluorescence intensity an body amount sufficient allow the accumulate fluid tissue, exposing tissue excitation light, measuring fluorescent emission light from determining level by comparing measured intensity. This preferably uses comprising pyrenebutyric acid its salt form.
