From: Improvement of amperometric transducer selectivity using nanosized phenylenediamine films
Optimal method of PD polymerization | Type of electrode | Optimal isomer of PD | Duration of the electrode preparation | Effectiveness of blocking properties | Storage stability | Biosensor application | Ref. |
|---|---|---|---|---|---|---|---|
CV (from − 0.3 V to +0.9 V vs. Ag/AgCl) | Pd disk | m-PD | 48 min | Full blocking of AA, cys, acetaminophen. Small interference from UA | N/A | N/A | [8] |
Constant potential (+0.7 V vs. Ag/AgCl) | Ru-covered carbon fiber ME | m-PD | 45 min | Full blocking of UA, cys, acetaminophen, DA. Small interference from AA—addition of ascorbate oxidase to remove it | > 2 days | Glucose, lactate and glutamate biosensors, in vivo analysis in rat brain | [6] |
Constant potential (+0.7 V vs. SCE) | Pt–Ir cylinders ME | o-PD | 15 min | Full blocking of AA | > 7 days | N/A | [7] |
CV (from −0.25 V to +0.9 V vs. SCE) | Glassy carbon electrode | o-PD | 15 min | Full blocking of AA, UA and DA | > 15 days | N/A, H2O2 detection in human serum samples | [9] |
Constant potential (+0.7 V vs. Ag/AgCl) | Pt cylinders ME | o-PD | 15 min | Full blocking of AA | N/A | N/A | [13] |
CV (from 0 V to +0.9 V vs. Ag/AgCl) | Pt disk | m-PD | 6 min | Full blocking of AA, cys, UA, DA | > 8 days | Human serum samples and cell lysate | This work |
