photosensitized oxidation
1.The luminol chemiluminesence in the photosensitized oxidation of NAD(P)H was found to be dependent upon many factors such as pH,laser density, irradiation time,concentrations of luminol, HPD and NAD(P)H.
2.Singlet oxygen (1O2) produced by illuminated photosensitizer Rose Bengal was delected by means of bleaching of N, N-dimethyl- nitrosoaniline (DMNA) . The 1O2 could be scavenged by green lea extracts (GTE) , and the scavenging effects were obviously at beginning of photosensitized oxidation.
3.When the concentration of NAD(P)H was far more excessive as compared with that of hematoporphyrin derivative (HPD) , the intensity of CL was positively proportional to the concentration of HPD, which implied that the CL measurement can be used as an indicator for the detection of photosensitized oxidation and that the CL may be generated by the photooxidation of NAD(P)H in the presence of reactive oxygen species(ROS).
