Comparative operational stability of different biosensor constructs.
| Biosensor Construct | Treatment 1 | Operational Stability, ∆, % |
|---|---|---|
| SPE/MnO2/P(NIPAM-co-APMA)/ChO | + GA | −0.16 ± 0.13 |
| − GA | −3.53 ± 1.12 | |
| SPE/MnO2/P(NIPAM-co-DMAPMA)/ChO | + GA | −4.20 ± 0.79 |
| − GA | −4.21 ± 0.78 |
1 + Glutar aldehyde (GA) means a treatment of the resultant surface with 1% aqueous GA solution for 1 h; − GA means a treatment of the reference surface with water for 1 h. SPE stands for a screen-printed electrode.
