Prussian Blue Based Nanoelectrode Arrays for H2O2 Detection

Abstract: We propose to form nanoelectrode arrays by deposition of the electrocatalyst through lyotropic liquid crystalline templates onto inert electrode support. Whereas Prussian Blue is known to be a superior electrocatalyst in hydrogen peroxide reduction, carbon materials used as electrode support demonstrate only a minor activity. We report on the possibility for nanostructuring of Prussian Blue by its electrochemical deposition through lyotropic liquid crystalline templates, which is noticed from atomic force micr… Show more

“…The detection limit was estimated to be 1.6 mmol·L -1 (S/N = 3). From the slope of 5.15 × 10 -3 mA·mM -1 , the sensitivity of the proposed Hb biosensor was 0.16 A·M -1 ·cm -2 , which was larger than that of 0.06 A·M -1 ·cm -2 and 0.045 A·M -1 · cm -2 , 40,41 and slightly lower than that of 0.6 A·M -1 ·cm -2 and 0.234 A·M -1 ·cm -2 . 42,43 The high sensitivity of Hb modified electrode was due to the electrochemical characterization of intrinsic peroxidase activity of Hb.…”

“…3,4,6,7,11,12 The decrease in applied voltages, with avoidance of interfering signals, provides a more specific and accurate detection; thus, PB-modified electrodes have been recently adopted in many amperometric measurements for H2O2. 4,13 Regular configuration of amperometric measurements for H2O2 consists of a conductive lead connected to a surfacemodified electrode, on which a PB layer is deposited. Various methods, such as spontaneous chemical reactions, 11,12,14,15 potential cycling method 4,7 and galvanostatic method, 8,9,[16][17][18][19][20][21] have been proposed to modify electrode surfaces.…”
