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

Calixarene modified montmorillonite: A novel design for biosensing applications

SÖNMEZ, Burak | SAYIN, Serkan | YALÇINKAYA, Esra Evrim | AĞ SELECİ, Didem | YILDIZ, Hüseyin Bekir | ODACI DEMİRKOL, Dilek | TİMUR, Suna

Here we report the synthesis, characterization and application of calixarene (Calix) modified montmorillonite (Mt) as a platform for bio-applications such as biomolecule immobilization and biosensing technologies. This modification enhanced the biomolecule immobilization capability of Mt. Initially, amino-functionalised calixarenes (Calix-NH2) were synthesized and used as a modifier. X-ray diffraction, Fourier transform infrared spectroscopy, zeta potential and thermal gravimetric analysis were performed to verify the modification of the clay minerals. For the biosensor construction, Calix-NH2 ...Daha fazlası

Synthesis of Various Calix [4] arene Derivatives with Mercaptoalkyl Chains and Their Application in Removing Cr (VI) from Aqueous Solution

SAYIN, Serkan | YILDIZ, Hüseyin Bekir | EYMÜR, Serkan

Four different mercaptoalkyl-substituted calixarene derivatives (5,11,17, 23-tetra-tert-butyl-25,27-bis(3-mercaptopropoxyl)-26,28-dihydroxycalix [4]arene, 25,27-bis(3-mercaptopropoxyl)-26,28-dihydroxycalix[4]arene, 25,27-bis(5-mercaptopentanoxyl)-26,28-dihydroxycalix[4]areneand5,17di-tert-butyl-11,23-di-carboxyl-26,28-bis(3-mercaptopropoxyl)-25,27-dihydroxycalix[4]arene) were synthesized. Their structures were characterized by Fourier transform infrared spectroscopy (FTIR), 1H and 13C NMR spectroscopy, and elemental analysis techniques. Moreover, their extraction capabilities at different para ...Daha fazlası

A Novel Architecture Based On A Conducting Polymer And Calixarene Derivative: İts Synthesis And Biosensor Construction

GÖKOĞLAN, Tuğba Ceren | SÖYLEMEZ, Saniye | KESİK, Melis | ÜNAY, Hande | SAYIN, Serkan | YILDIZ, Hüseyin Bekir | ÇIRPAN, Ali | TOPPARE, Levent

In this study, a novel amperometric glucose biosensor based on a selenium comprising conducting polymer and calixarene was developed. Firstly, poly(2-(2-octyldodecyl)-4,7-di(selenoph-2-yl)-2H-benzo[d][1,2,3]triazole), poly((SBTz)) was electrodeposited onto a graphite electrode by an electropolymerization technique. Then, a newly synthesized calixarene and gold nanoparticle (AuNP) mixture was used for the improvement of biosensor characteristics. GOx, as a model enzyme was immobilized on the modified electrode surface. The constructed surface serves as a sufficient immobilization platform for t ...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
