Figure 4

Optical response of DOS/PVC microspheres based on ionophore IX (top) and X (bottom) expressed as the mole fraction of the protonated chromoionophore (ETH 5418, see Experimental). The sensing particles were immobilized on glass slides. The AgNO3 solutions were applied in Mg(OAc)2 buffer at pH 4.7 or MOPS buffer at pH 7.4. The theoretical response curves (solid lines) were calculated with the same exchange constant at both pH values.
