“…One of these applications is, for example, as a typical nonconducting film and effective barrier to protect the electrode from fouling. POAP films have been successfully employed in the development of hydrogen peroxide, glucose, and uric acid biosensors 10,20,29,49,50 . Recently, OAP has been utilized as monolayer 51 and as aniline copolymer 3 on glassy carbon electrode.…”

“…One of such conditions is the substrate selected for the obtention of a conductive polymer. Among the commonest substrates utilized for this purpose are glassy carbon [1][2][3][4][5][6][7][8][9] , platinum 2,4,5,7,8,[10][11][12][13][14][15][16][17] , gold 4,7,[18][19][20][21][22][23][24][25][26][27] , carbon paste 28,29 , transparent indium tin oxide 18,19,30 , Cu 18 , Ag 31 , SnO 2 32 , etc. However, it is always advisable to employ other electrodic substrates for the fabrication of modified electrodes.…”

In the present work the obtention of poly-o-aminophenol (POAP) at high potentials on conducting glass (SnO 2 : F) is reported. The synthesis was carried out by continuous potential cycling in a 1×10 -3 M o-aminophenol (OAP), 0.1 M hydrochloric acid, and 0.1 M potassium chloride solution between -0.2 and 1.5 V at 0.05 V·s -1 vs Ag│AgCl. The polymer growth was followed by cyclic voltammetry, UV-vis spectra, and AFM characterization. The SnO 2 : F modified electrode (SnO 2 : F/POAP) was tested in the electro-oxidation of ascorbic acid (AA) in phosphate buffer solution. This coating showed an important electrocatalytic effect because a negative anodic shift of 0.4 V with respect to a bare SnO 2 : F glass electrode was observed.

“…Research on improving the electron transfer has been focused on the mediators and conductive polymers, where Ferrocene derivatives and Prussian blue have been used as mediators [1][2][3][4][5][6]. Similar conducting polymers such as polypyrrole, polyoxane, poly(ethylene oxide), and poly(toluidine blue O) are also used as mediating conductive polymers [3,[7][8][9].…”

A novel glucose sensor was constructed, and its analytical potential examined. A chip-type three-electrode system for use in a flow-type electrochemical glucose sensor was fabricated using a UV lithography technique on a glass slide. An Ag/AgCl reference electrode was made by electroplating silver onto a Pt electrode and dipping in a saturated KCl solution for 30 min. In addition, a glucose-sensing electrode was fabricated using a two-photon adsorbed photopolymerization technique with a photo-reactive resin containing a glucose oxidase enzyme, ferrocene mediator, non-ionic surfactant, and carbon nanotubes. The cyclic voltammetry of the potassium ferrocyanide in the Pt sensor system showed a stable electrode condition. The response of the modified Pt sensor confirms the feasibility of using a two-photon adsorbed photopolymerization technique for the easy fabrication of functional biosensors.

“…In fact, although the first generation biosensors are still widely used, the principal drawback is that H 2 O 2 is sensed at a high potential (+0.70 V vs. Ag|AgCl) on most electrode materials and possible interfering components present in biological fluids such as ascorbic acid (AA), uric acid (UA) and acetaminophen (APAP) can be oxidized at this high potential and generate a faradic current that interferes in the measurement of the analyte [3,4]. In order to minimize the oxidation of interfering components, it is preferred to work in a potential range from À0.2 to +0.15 V vs. Ag|AgCl [5,6]. To overcome the problem of interferences in a real matrix, the research was focused on developing different strategies.…”

a b s t r a c tIn this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists of the electrodeposition of nanocoral Au onto a gold substrate using hydrogen as a dynamic template in an ammonium chloride solution. After that, the Pt nanostructures were deposited onto the nanocoral Au organized in pores. Using Pt (II) and Pt (IV), we realized nanocoral Au decorated with Pt nanospheres and nanocoral Au decorated with Pt nanoflowers, respectively. The bimetallic nanostructures showed better capability to electrochemically oxidize hydrogen peroxide compared with nanocoral Au. Moreover, Au-Pt nanostructures were able to lower the potential of detection and a higher performance was obtained at a low applied potential. Then, glucose oxidase was immobilized onto the bimetallic Au-Pt nanostructure using cross-linking with glutaraldehyde. The biosensor was characterized by chronoamperometry at +0.15 V vs. Ag pseudo-reference electrode (PRE) and showed good analytical performances with a linear range from 0.01 to 2.00 mM and a sensitivity of 33.66 mA/mM cm 2 . The good value of K m app (2.28 mM) demonstrates that the hybrid nanostructure is a favorable environment for the enzyme. Moreover, the low working potential can minimize the interference from ascorbic acid and uric acid as well as reducing power consumption to effect sensing. The simple procedure to realize this nanostructure and to immobilize enzymes, as well as the analytical performances of the resulting devices, encourage the use of this technology for the development of biosensors for clinical analysis.
