Table 6

Determination of CPM and PSE in spiked human plasma by the proposed sensors 3 and 6.

Drug concentration	Spiked human plasma
	Sensor 3	Sensor 6
	Recovery (%) ± SD
10^−5 M	101.12 ± 0.716	100.41 ± 1.215
10^−6 M	100.60 ± 1.158	100.31 ± 1.040
10^−7 M	101.78 ± 0.618	101.39 ± 0.622

The recovery percentages are the average of three determinations.
