A Novel Immobilization Matrix For The Biosensing Of Phenol: Self Assembled Monolayers Of Calixarenes

TAŞÇI, Filiz | SAYIN, Serkan | AĞ SELECİ, Didem | DEMİR, Bilal | AZAK, Hacer | YILDIZ, Hüseyin Bekir | ODACI DEMİRKOL, Dilek | TİMUR, Suna

Aim: The development of calixarene based phenol biosensor. Methods: This study describes the application of a calixarene derivative, 5,17-diamino-25,27-bis(3-thiol-1-oxypropane)-26,28-dihydroxycalix[4]arene (HS-Calix-NH2) which has both amino and thiol functionalities, in the practical surface modifications for biomolecule binding. The structure of HS-Calix-NH2 allows easy inter-action with Au surface and one-step biomolecule immo-bilization. Self-assembled monolayers (SAMs) of p-amino-functionalized mercaptoalkylcalixarene (HS-Calix-NH2) were formed onto the Au electrode. Then, Laccase (Lac) ...Daha fazlası

Enzyme‐Based Biosensors in Food Industry via Surface Modifications (Chapter 7)

GAZEL, Nilay | YILDIZ, Hüseyin Bekir

Enzyme technology has received great attention with improvements in biological remediation techniques. Enzyme-based biosensors can qualify as a measuring system as they permit the detection of biological events by detecting biochemical changes in biological processes. Advantages of biosensors are identification of even small quantities, cost effectiveness, and requirement of less power and less volume for identifying a wide linear range for usage [1]. Moreover, biosensors have high sensitivity, selectivity, and good response time for different kinds of applications.

Construction of ferrocene modified conducting polymer based amperometric urea biosensor

DERVISEVIC, Muammer | DERVISEVIC, Esma | ŞENEL, Mehmet | ÇEVİK, Emre | YILDIZ, Hüseyin Bekir | ÇAMURLU, Pınar

Herein, an electrochemical urea sensing bio-electrode is reported that has been constructed by ﬁ rstly electropolymerizing 4-(2,5-Di(thiophen-2-yl)-1H-pyrrol-1-yl)aniline monomer (SNS-Aniline) on Pencil Graphite Electrode (PGE), then modifying the polymer coated electrode surface with di-amino-Ferrocene (DAFc) as the mediator, and lastly Urease enzyme through glutaraldehyde crosslinking. The e ﬀ ect of pH, temperature, polymer thickness, and applied potential on the electrode current response was investigated besides performing storage and operational stability experiments with the interferenc ...Daha fazlası

A photoelectrochemical device for water splitting using oligoaniline-crosslinked [Ru(bpy)2(bpyCONHArNH2)]+2 dye/IrO2 nanoparticle array on TiO2 photonic crystal modified electrode

YILDIZ, Hüseyin Bekir | BEZGİN ÇARBAŞ, Buket | SÖNMEZOĞLU, Savaş | KARAMAN, Mustafa | TOPPARE, Levent

This article describes the construction of photoelectrochemical cell system splitting water into hydrogen and oxygen using UV–vis light under constant applied voltage. Oligoaniline-crosslinked 2-(4-aminobenzyl)malonic acid functionalized IrO2·nH2O nanoparticles and visible light absorbing dye, [Ru(bpy)2(bpyCONHArNH2)+2] arrays on titanium dioxide (TiO2) photonic crystals modified electrodes were used as photoanode, and nanostructures based on bonding of Pt nanoparticles by using electropolymerization on poly 4-(2,5-di(thiophene-2-il)-1H-pyrrol-1-il)benzenamine P(SNS-NH2) conducting polymer mod ...Daha fazlası

Hydrophobic coating of surfaces by plasma polymerization in an RF plasma reactor with an outer planar electrode: synthesis, characterization and biocompatibility

KARAMAN, Mustafa | GÜRSOY, Mehmet | AYKÜL, Fatmanur | TOSUN, Zahide | DEMİREL KARS, Meltem | YILDIZ, Hüseyin Bekir

This paper presents the plasma polymerization of poly(hexa ﬂ uorobutyl acrylate)(PHFBA) thin ﬁ lms on different substrates in an RF plasma reactor with an outer planar electrode. This reactor con ﬁ guration allows large area uniformity and fast processing times. Deposition rates of up to 60 nm min−1 were observed. The in ﬂ uence of plasma power and substrate temperature on the deposition rate, structure and wettability of the as-deposited ﬁ lms was investigated. It was observed that better hydrophobicity was obtained at high plasma power and in low temperature conditions. PHFBA thin ﬁ lms depo ...Daha fazlası
