Beta-galactosidase Determination by an Electrochemical Biosensor Mediated with Ferrocene
Sezgintürk, Mustafa Kemal; Dinçkaya, Erhan (Informa Healthcare, 2011)In this paper, a new viewpoint on the activity determination of beta-galactosidase is reported. Glucose oxidase was directly immobilized on a glassy carbon electrode and mediated by ferrocene. The biosensor's performance ... -
A Biosensor Based on Zucchini (Cucurbita Pepo L.) Homogenate as a Biorecognition Layer for Ascorbic Acid Determination
Sezgintürk, Mustafa Kemal; Koca, Halit Buğra; Özben, Yavuz Selim; Dinçkaya, Erhan (Informa Healthcare, 2010)An amperometric biosensor based on zucchini (Cucurbita pepo) tissue homogenate is presented. The zucchini tissue homogenate was crosslinked with gelatine using glutaraldehyde and fixed on a pretreated teflon membrane. The ... -
A Biosensor for the Determination of beta-galactosidase Activity: A Different Viewpoint on Biosensors
Sezgintürk, Mustafa Kemal; Dinçkaya, Erhan (Informa Healthcare, 2011)beta-galactosidase splits lactose into glucose and galactose. Because of its biotechnological interest, we presented a biosensor system in order to monitor beta-galactosidase activity. Immobilization steps of the biosensor ... -
Construction and Comparison of Trametes versicolor Laccase Biosensors Capable of Detecting Xenobiotics
Sezgintürk, Mustafa Kemal; Odacı, Dilek; Pazarlıoğlu, Nurdan; Pilloton, Roberto; Dinçkaya, Erhan; Telefoncu, Azmi; Timur, Suna (Informa Healthcare, 2010)Amperometric biosensors using laccase from Trametes versicolor as a bioelement were developed for 2,4-dichloro phenoxy acetic acid (2,4-D). Laccase enzyme was immobilized by gelatin and glutaraldehyde onto a Clark oxygen ... -
Development of an impedimetric aflatoxin M1 biosensor based on a DNA probe and gold nanoparticles
Dinçkaya, Erhan; Kinik, Ozer; Sezgintürk, Mustafa Kemal; Altuğ, Çağrı; Akkoca, Aylin (Elsevier Advanced Technology, 2011)The present work describes the construction and application of a new DNA biosensor for detection of aflatoxin M1. In order to immobilize a thiol-modified single stranded DNA (ss-HSDNA) probe that specifically bound aflatoxin ... -
Glutathione (GSH) Determination by a Very Simple Electrochemical Method
Sezgintürk, Mustafa Kemal; Dinçkaya, Erhan (Springer, 2011)Glutathione (GSH; gamma-glutamylcysteinylglycine) is ubiquitous in mammalian and other living cells. It contains an unusual peptide linkage between the amine group of cysteine and the carboxyl group of the glutamate side ... -
A Hybrid Enzyme Biosensor Based on Sulfite Oxidase and Glucose Oxidase for the Analyzing of Sulfite and Glucose
Sezgintürk, Mustafa Kemal; Alaçam, Sencer; Altuğ, Çağrı; Akbayırlı, Pınar; Dinçkaya, Erhan (Univ Tehran, Fac Chemistry, Center Excellence Electrochemistry, 2012)In this study, we developed a hybrid biosensor based on sulfite oxidase and glucose oxidase for determination of sulfite and glucose. The principle of the measurements was based on the determination of the decrease in the ... -
