A novel imaging method exploiting the photophysics of fluores- cent markers is presented, where the contrast depends on the triplet state kinetics, which are considerably slower than the sin- glet state kinetics. This makes it more sensitive to the microenvi- ronment [1]. A biological assay of oxygen consumption upon smooth muscle cell contraction is presented.
