A bio-imprinted urease biosensor: Improved thermal and operational stabilities
Teke, Mustafa; Sezginturk, Mustafa Kemal; Dinckaya, Erhan; Telefoncu, Azmi (Elsevier Science Bv, 2008)Despite the increasing number of applications of biosensors in many fields, the construction of a steady biosensor remains still challenging. The high stability of molecularly bio-imprinted enzymes for its substrate can ... -
A biosensor based on graphite epoxy composite electrode for aspartame and ethanol detection
Anık, Ülkü; Odacı, Dilek; Timur, Suna; Merkoci, Arben; Alegret, Salvador; Besun, Nurgun; Telefoncu, Azmi (Elsevier Science Bv, 2006)A gelatin membrane with carboxyl esterase and alcohol oxidase was subsequently integrated onto the surface of a graphite epoxy composite electrode (GECE). The developed biosensors showed linearity in the range of 2.5-400 ... -
Effects of mediators on the laccase biosensor response in paracetamol detection
Odaci, Dilek; Timur, Suna; Pazarlioglu, Nurdan; Anık, Ülkü; Telefoncu, Azmi (Wiley, 2006)An enzyme electrode suitable for paracetamol detection was developed by immobilizing laccase on a dissolved-oxygen probe surface. The immobilization procedure was achieved by means of gelatin, which was then cross-linked ... -
Graphite epoxy composite electrodes modified with bacterial cells
Anık, Ülkü; Odaci, Dilek; Timur, Suna; Merkoci, Arben; Pazarlioglu, Nurdan; Telefoncu, Azmi; Alegret, Salvador (Elsevier Science Sa, 2006)The modification of a graphite-epoxy composite electrode (GECE) with bacterial cells along with an analytical application are presented. Pseudomonas putida DSM 50026 was used as a biological component and the measurement ... -
Immobilization of pancreatic lipase on chitin and chitosan
Kılınç, Ali; Teke, Mustafa; Önal, Seçil; Telefoncu, Azmi (Taylor & Francis Inc, 2006)In this study, porcine pancreatic lipase (EC 3.1.1.3) was immobilized on chitin and chitosan by adsorption and subsequent crosslinking with glutaraldehyde, which was added before (conjugation) or after (crosslinking) washing ... -
Purification of bovine pancreatic phospholipase A(2) by an affinity ultrafiltration technique
Teke, Mustafa; Telefoncu, Azmi (Elsevier Science Bv, 2008)Phospholipase A(2) (PLA(2); EC 3.1.1.4) is a lipolytic enzyme that hydrolyze phosphoglycerides at the acyl ester bond at the sn-2-position into the corresponding lysophospholipid and fatty acid. Mammalian PLA(2) enzymes ... -
Two biosensors for phenolic compounds based on mushroom (Agaricus bisporus) homogenate: Comparison in terms of some important parameters of the biosensors
Teke, Mustafa; Sezgintuerk, M. Kemal; Dinckaya, Erhan; Telefoncu, Azmi (Taylor & Francis Inc, 2008)Interest in molecular imprinted polymer techniques has increased because they allows for the improvement of some stability characteristics of enzymes. The high stability of molecularly imprinted enzymes for a substrate can ...
