The electrode exhibited good electrocatalytic activity with a well-defined hyperbolic dependence of amperometric signal upon glucose concentration in the presence and in the absence of oxygen. The electrode showed a good reproducibility and repeatability with relative standard deviation of less than 3 and 5%, respectively. The interaction of GOx with PD mediator was confirmed by means of UV?Vis absorbance spectroscopy.en10.1134/S1061934816010044info:eu-repo/semantics/closedAccessphenanthroline derivative1,10-phenanthroline-5,6-dioneglucose oxidaseglucose biosensoramperometric sensorselectrocatalytic activityArticle7117781Q4WOS:000367261200010Q4
