Detection of Singlet Oxygen

Analysis of the reaction rates is achieved in terms of oxygen uptake measured with an oxygen electrode, or by product separation and quantification. DPBF absorbs intensely at 415 nm and reacts rapidly with singlet oxygen to form a colorless intermediate endoperoxide. The DPBF reaction can be used as a benchmark against which the effect of an added quencher is compared. A note of caution must be applied the use of inhibitors and quenchers alone is not unambiguous in its outcome and should be strictly supplemented with flash photolysis experiments. Thus, if a photosensitized reaction is quenched by millimolar concentrations of azide ion, it should also be established that azide does not quench the triplet state of the sensitizer directly because that would also affect the reaction rate. [Pg.28]

It has been suggested but now seems rather improbable, that singlet oxygen may be involved in this phagocytosis chemiluminescence [118]. This conclusion is supported experimentally by means of the most reliable method available at present for the chemical detection of singlet oxygen its unambiguous reaction with cholesterol (p. 13). [Pg.181]
