Figure 4

The effect of pH on the potential stability of a DB-sensor using two concentrations of DB; 1.0 and 0.1 mM as shown in the upper blue and lower red lines respectively. Minimal emf changes for pH values between 3 and 8 were observed. Each point is the average of six measurements while the error bars shown represent the RSD values of the six measurements.
