Figure 3.zip

Average threshold voltages were calculated from transfer curves of surface MBP & cortisol antibody analyte control experiment, surface BSA & MBP antibody analyte control experiment and surface MBP & anti-MBP analyte main experiment. The changes of threshold voltage are indicated in this figure when different concentrations of MBP antibody were added for the main experiment. All the experiments were repeated at least on 4 samples. The inset indicates the average value.
