Amperometric biosensors based on alcohol oxidase (AOX) immobilized on the conducting polymers of 3,4-ethylenedioxythiophene (PEDOT) and 4,7-dithien-2-yl-2,1,3-benzothiadiazole (TBTD) were constructed. Proposed biosensors were characterized using ethanol as the substrate and the responses were measured. Kinetic parameters, I-max, K-m and sensitivity were determined for the biosensors with or without TBTD. Optimization studies for TBTD thickness, PEDOT amount and pH were carried out. The biosensing capacity was discussed for TBTD matrix.

A thiazolothiazole containing multichromic polymer for glucose detection Soylemez, S.; Kaya, H. Z.; Udum, Y. A.; Toppare, Levent Kamil (Department of Polymer Engineering, Scientific Society of Mechanical Engineering, 2019-10-01) Donor-acceptor (DA) type monomers namely 2,5-di(thiophen-2-yl)thiazolo[5,4-d]thiazole (TTzTh) and 2,5-bis(3-methylthiophen-2-yl)thiazolo[5,4-d]thiazole (TTzMTh) were synthesized and their electrochemical and optoelectronic properties were investigated in detail. The spectro-electrochemical analysis showed that the alkyl chain substitution results in a shift in the onset of the pi-pi* transition towards longer wavelengths. Depending on the donor substituents, the polymers exhibited optical band gaps 1.65 and...
A novel multi-electrochromic polymer based on selenophene and benzotriazole via electrochemical and chemical polymerization Demir, Fatma; Keles, Duygu; Karabag, Aliekber; Çırpan, Ali; Toppare, Levent Kamil (Informa UK Limited, 2019-03-04) In this study, a novel donor-acceptor type monomer was designed based on selenophene and benzotriazole with a bulky pendant group and synthesized through Stille coupling reaction. The monomer was polymerized electrochemically by using cyclic voltammetry and also chemically by oxidation in the presence of FeCl3. Both polymers were then compared in terms of their optical properties, electrochemical and spectroelectrochemical behaviors, kinetic and colorimetric properties and surface morphologies. Independent ...
Contribution of Nanoclays to the Performance of Traditional Flame Retardants in ABS Ozkaraca, Ayse Cagil; Kaynak, Cevdet (Wiley, 2012-03-01) The purpose of this study was to investigate contribution of nanoclays to the flame retardancy performance of a traditional brominated flame retardant compound with various combinations of antimony trioxide and zinc borate. The matrix polymer acrylonitrile butadiene styrene (ABS) was compounded by melt mixing in a laboratory size twin-screw extruder. X-ray diffraction analysis and transmission electron microscopy revealed that nanoclay silicate layers were mainly intercalated with certain level of exfoliati...
Characterization and potential applications of immobilized glucose oxidase and polyphenol oxidase Ekinci, Olcun; Boyukbayram, A. Elif; Kiralp, Senem; Toppare, Levent Kamil; Yagci, Yusuf (Informa UK Limited, 2007-07-01) Pyrrole functionalized polystyrene (PStPy) was copolymerized with pyrrole to obtain a conducting copolymer, P(PStPy-co-Py) which is used as the immobilization matrix. Glucose oxidase and polyphenol oxidase enzymes were immobilized via the entrapment method by electrochemical polymerization. Enzyme electrodes were prepared by electrolysis at a constant potential using sodium dodecyl sulfate (SDS) as the supporting electrolyte during the copolymerization of PStPy with pyrrole. Maximum reaction rates (V-max) a...
A new donor-acceptor type polymeric material from a thiophene derivative and its electrochromic properties Udum, Yasemin Arslan; Yildiz, Ersin; Günbaş, Emrullah Görkem; Toppare, Levent Kamil (Wiley, 2008-06-01) A new electrochromic polymer, poly(2,3,5,8-tetra(thiophen-2-yl)quinoxaline) (PTTQ), was synthesized electrochemically and its electrochromic properties were investigated. The polymer was characterized by Cyclic Voltammetry, Fourier Transform infrared spectroscopy, LTV-Vis-NIR Spectroscopy, and colorimetry. Spectroelectrochemistry analysis demonstrated that the polymer can undergo both p- and true n-type doping processes. The polymer, (PTTQ), has three accessible color states: an oxidized transmissive, a neu...
