Figure 2. The yields of the nitroxide radical from the laser-irradiated photosensitizers.

The mixture containing 450 mM TPC and 10 µM photosensitizer was irradiated by the laser light with a wavelength of 532 nm for 15, 30, 45 and 60 s. Each value represents the mean of triplicate determinations with standard deviation. The slope and intercept of each regression line are expressed as the mean with standard error.
