Figure 4From: Light triggered detection of aminophenyl phosphate with a quantum dot based enzyme electrodeDose response curve for detection of 4AP (originally dissolved in 25% methanol and 75% phosphate buffer pH 5) as recorded in phosphate buffer pH 7.8 at bias potential of +200 mV for geometries a) S 0 , b) S 1 , c) S 2 , d) I 1 , e) I 2 . The resulting photocurrent I is plotted versus the concentration c of 4AP.Back to article page
