These roughened surfaces cause a scattering of light at the interface that extends the optical path, with the gas pores in the mesoporous ZnO also functioning as a secondary light-scattering center.From the optical properties of the four AZO substrate types shown in Figure 4, it is clear that their reflectance values are almost comparable to, or slightly less than, the reference sample.
Moreover, we improved the cost-efficiency of the overall assay by decreasing the reagents' concentrations of the secondary (light-producing) reaction, while ensuring that they do not become rate-limiting for the processing of the PPi product of the primary (polymerase) reaction.
In addition to their role as secondary light-absorbing pigments, carotenoids, and β-carotene in particular, are able to reduce the Chl triplet state and to prevent the formation of the harmful singlet oxygen or to scavenge it after its production by the interaction of triplet chlorophyll with O2 (Ramani et al. 2006).
