The enhancement mechanism was determined based on the emissions of [Ru(dpp)3]Cl2 on dye concentration dispersed on the PMMA PhCs and temperature. The PMMA PhC/Ru complex composites were also used for assistant intracellular oxygen sensing and cell imaging, which effectively improved the LOD and ...

Cells exposed to [{(bpy2Os-(dpp)}2RhCl2]Cl5 at concentrations of 5.5-110 µM, rinsed, and illuminated showed only inhibition of cell growth. The impact of [{(bpy2Ru(dpp)}2RhCl2]Cl5 and [{(bpy2Os(dpp)}2RhCl2]Cl5 on cell growth following illumination shows the promise of this ...
The long emission lifetime of the [Ru(dpp)3]2+ dye, together with the low efficiency of its thermally-activated deactivation process (ηt), probably mean that the observed decrease of its luminescence upon increasing temperature is due to both decay pathways. This fact would explain the ...
