Development of the piezoelectric biosensor for acetochlor detection

Popis výsledku v původním jazyce

The piezoelectric immunosensor for the determination of acetochlor was developed. The surface of gold electrodes of piezoelectric quartz crystals was modified by self-assembled thiolayers using either 4-aminothiophenol or dithiobis(succinimidyl propionate). In the next step, the modified surface was used for the coupling of acetochlor-protein conjugates. Acetochlor was conjugated to ovalbumin using either thiopropionic acid or acetylthiosuccinimidyl anhydride (AMSA). The acetochlor-modified crystals were used for characterization of the anti-acetochlor polyclonal antibody (Ab). The kinetic rate and equilibrium constants were compared for both types of immobilization. For acetochlor immobilized through AMSA, the dissociation rate constant was 20-times lower. The possibility of using this system for the competitive determination of free acetochlor in water was further studied. The detection limit (10% decrease of relative binding of the antibody) was 0.20 mg/l). The piezoelectric crystal
