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

Synthesis and characterization of a new poly (dithieno (3, 2-b: 2′, 3′-d) pyrrole) derivative conjugated polymer: Its electrochromic and biosensing applications

AZAK, Hacer | YILDIZ, Hüseyin Bekir | ÇARBAŞ, Buket

Synthesis and electropolymerization of a new conjugated dithieno(3,2-b:20,30-d) pyrole (DTP) derivative, namely, 2-(2-(2-(4H-dithieno[3,2-b:20,30-d]pyrrol-4-yl)ethoxy)ethoxy)ethanamine, (DTP-alkoxy-NH2) monomer are presented. The electrochemical, spectroelectrochemical effects and biosensor capability towards to glucose oxidase enzyme of P(DTP-alkoxy-NH2) polymer fi lm are investigated in detail during the placement of alkoxy-NH2 functional unit in the polymer. Electrochemical and optical results between neutral and oxidized states of the polymer fi lm show that (P(DTP-alkoxy-NH2)) has reversibl ...Daha fazlası

Folic-Acid-Modified Conducting Polymer: Electrochemical Detection of the Cell Attachment.

AZAK, Hacer | BARLAS, Fırat Barış | YILDIZ, Hüseyin Bekir | GÜLEÇ, Kadri | DEMİR, Bilal | ODACI DEMİRKOL, Dilek | TİMUR, Suna

Here, postfunctionalization and bioapplication of a π-conjugated polymer named 4-[4H-dithieno(3,2-b:2',3'-d)pyrrol-4-yl]aniline (DTP-aryl-NH2 ) are reported, which is successfully synthesized via electropolymerization onto the glassy carbon electrode. Folic acid (FA) is used to modify the amino functional polymer via N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride/N-hydroxysuccinimide chemistry for the further steps. The selective adhesion of folate receptor positive cells on the surface is followed by the electrochemical methods. Cyclic voltammetry and electrochemical impedance s ...Daha fazlası

Calixarene assembly with enhanced photocurrents using P(SNS-NH2)/CdS nanoparticle structure modified Au electrode systems

SAYIN, Serkan | AZAK, Hacer | YILDIZ, Hüseyin Bekir | ÇAMURLU, Pınar | UYSAL AKKUŞ, Gülderen | TOPPARE, Lale | ERSÖZ, Mustafa

Two novel calix[n]arene-adorned gold electrodes producing high photocurrent intensities were successfully constructed by embedding gold electrode surfaces with both P(4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine) conducting polymer and 4-mercaptoboronic acid-functionalized semiconductor CdS nanoparticles to facilitate the binding of calix[n]arene sulfonic acids with nanoparticles. This structure enabled an electron transfer cascade that both induced effective charge separation and efficiently generated photocurrent. The prepared electrodes were used to generate photocurrent by relying o ...Daha fazlası
