Photobleaching of 0.15 mM 9,10-anthracenediyl-bis(methylene)dimalonic acid (ABMDMA) by singlet oxygen generated by (i) void silica nanoparticles as control; (ii, iii) 2 μM Pc4SNP and Pc4 water solution. The change in ABMDMA absorption at 400 nm was measured as a function of irradiation time. Inset: absorption spectra of 0.15 mM ABMDMA water solution containing 2 μM Pc4SNP as a function of irradiation times (0 to 360 sec). Values are the means ± SEM (n = 3).
