3.7. ReactiÕation of enzyme by PAM-2 BSA membrane
As one can see from Fig. 8a, the sensor response was almost reversible for a 10 min incubation if the concentration of the pesticide is close to 10y5 M, whereas for higher Ž y3 concentration 10 M only a partial recovery of the . sensor occurs. From Fig. 8b, in the case of 10y5 M trichlorfon solution, the sensor response was almost reversible for a 10 min incubation with the pesticide solution, whereas after 60 min, only a partial recovery of the sensor response occurs. So, the complete recovery of the biosensors response after the performed pesticide assay was possible under certain conditions.
