Smaller PP-IX nanostructures have higher oxidizing potential.A, quantum yield of different-sized PP-IX nanostructures (average of three independent experiments ±standard deviation). All five combinations showed statistically significant (p < 0.05) difference, except pH 4.5 versus pH 7.4 (see Table S1). B, fluorescence emission spectra of FMN (21 μM) ± PP-IX (50 μM) at pH 7.4 were recorded after exciting the solutions at 400 nm. The data is representative of three independent experiments. C, PP-IX-mediated FMN oxidation at the indicated pH and PP-IX concentrations (average of three independent experiments ±standard deviation).
