Singlet oxygen ( 1 O 2 ) can be generated in a living cell upon focused laser irradiation of the intracellular photosensitizers. 1 O2 lifetime in the living cells is shortened by the reactions with cellular molecules, and thus the 1 O2 diffusion in a single cell has attracted much attention. In this
Singlet oxygen generation is reported from (1) enzymatic reaction and (2) electron transfer reactions of the superoxide anion measured directly with an ultrasensitive near-IR emission spectrophotometer by monitoring the Oz('A,) + O2 (32,-) transition at 1268nm. Near-IR emission spectra from the myel
