Abstract
This paper reports the utilization of a micropore electrode as platform for the development of a nonenzymatic glucose microsensor. To facilitate direct glucose oxidation, a highly porous Pt (pPt) layer was deposited electrochemically on the Pt disk base in the pore. Compared to a pPt deposited planar Pt disk electrode, the higher sensitivity and selectivity of the pPt deposited micropore electrode could not only be attributed to the increased electrode roughness, but also to the small pore opening functioning as an efficient mass-transport resistance to the interfering species. The prepared pPt-micropore electrode also showed improved potentiometric responses to pH changes. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
