Abstract :
The saturation intensity and photobleaching lifetime of tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) chloride (Ru(dpp)3) are measured and applied to the design of oxygen sensitive optodes for enzymatic biosensors. Photobleaching limits the excitation intensity in practical sensor systems.
