A new approach was developed using a combination of a conducting polymer; poly(3,4-ethylenedioxythiophene) (PEDOT) with the electrochemically produced polymer of N-ferrocenyl-3-(1H-pyrrol-1-yl) aniline, (PFcPyBz) layer for the enzyme scaffolding resulting in excellent analytical parameters. To organize such a surface, graphite electrode was coated with a PEDOT layer and it was used as a transducer for electrochemical deposition of the polymer of a newly synthesized FcPyBz monomer. Using a PEDOT layer as the working electrode improved localization of the PFcPyBz on the transducer surface while enhancing the biosensor performance. A simple binding of glucose oxidase (GOx) as a test enzyme on this new polymeric platform was achieved using glutaraldehyde (GA) as the cross linker. The low limit of detection and high sensing sensitivity on glucose for the biosensor are estimated as 54 mu M and 112.2 mu A/mMcm(2), respectively. The surface characterizations of the modified electrodes were investigated by cyclic voltammetry (CV), attenuated total reflectance-fourier transform infrared (ATR-FTIR) spectroscopy and scanning electron microscopy (SEM) techniques. Finally, different kinds of beverages were tested for sensor reliability with high accuracy. (c) 2018 The Electrochemical Society.

Microfluidic and Fuel Adulteration Sensing by Using Chiral Metamaterial Sensor BAKIR, MEHMET; KARAASLAN, MUHARREM; Unal, Emin; Karadag, Faruk; Alkurt, Fatih Ozkan; ALTINTAŞ, OLCAY; Dalgac, Sekip; Sabah, Cumali (The Electrochemical Society, 2018-08-08) In this study, Chiral Metamaterial Sensor (CMS), which is designed by utilizing a Split Ring Resonators (SRR) has been employed to reveal the two different types of sensor applications by experimentally and numerically. These applications include purity demonstration of methanol, ethanol and isopropyl alcohol (IPA) and fuel adulteration applications for petrol. All of the validations have been realized by measuring the complex permittivity values and reflection coefficients by using a vector network analyze...
Design of a microbial sensor using conducting polymer of 4-(2,5-di(thiophen-2-yl)-1H-pyrrole-1-l) benzenamine Tuncagil, Sevinc; ODACI DEMİRKOL, DİLEK; Yidiz, Ersin; TİMUR, SUNA; Toppare, Levent Kamil (Elsevier BV, 2009-03-28) A microbial biosensor based on Gluconobacter oxydans cells immobilized on the conducting polymer of 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine (SNS-NH2) coated onto the Surface of graphite electrode was constructed. The proposed biosensor was characterized using glucose as the Substrate. The linear relation was observed in the range of 0.1-2.5 mM and defined by the equation y = 0.415x + 0.377 (R-2 = 0.986). Analytical characterization, effects of electropolymerization time, pH, cell amount and the ...
Paper Based Glucose Biosensor Using Graphene Modified with a Conducting Polymer and Gold Nanoparticles GOKOGLAN, Tugba Ceren; KESİK, Melis; SOYLEMEZ, Saniye; YÜKSEL, Recep; Ünalan, Hüsnü Emrah; Toppare, Levent Kamil (The Electrochemical Society, 2017-01-01) In this work a novel approach was reported for glucose detection using disposable paper based electrodes consisting graphene modified with a conducting polymer, glucose oxidase (GOx) and gold nanoparticles. For the first time, a conducting polymer; poly(9,9-di-(2-ethylhexyl)-fluorenyl-2,7-diyl)-end capped with 2,5-diphenyl-1,2,4-oxadiazole (PFLO) was spread over graphene coated papers and used as a matrix for glucose detection. To finalize the desired biosensor, the enzyme GOx was immobilized with gold nano...
Sequential Deposition of Electrochromic MoO3 Thin Films with High Coloration Efficiency and Stability Turel, Onur; Hacioglu, Serife O.; Coskun, Sahin; Toppare, Levent Kamil; Ünalan, Hüsnü Emrah (The Electrochemical Society, 2017-01-01) Effect of thin film deposition route on the morphology and performance of molybdenum oxide (MoO3) based electrochromic devices was investigated. For the deposition of thin films, a sequential deposition method, which includes ultrasonic spray pyrolysis (USP) and thermal evaporation methods was used. Films deposited solely using either USP or thermal evaporation method were used as control samples. Following deposition, MoO3 thin films were then characterized using X-ray diffraction, X-ray photoelectron spec...
Stability analysis of graphene nanoribbons by molecular dynamics simulations Dugan, N.; Erkoç, Şakir (Wiley, 2008-04-01) In this work, stability of graphene nanoribbons are investigated using molecular dynamics. Simulations include heating armchair and zigzag-edged nanoribbons of widths varying between one and nine hexagonal rings until the bonds between carbon atoms start to break. Breaking temperatures and binding energies per atom for different widths are presented for both armchair and zigzag-edged cases. A nontrivial relation between stability and width is observed and discussed.
