alpha-glucosidase based bismuth film electrode for inhibitor detection
Timur, Suna; Anık, Ülkü (Elsevier, 2007)A biosensing system based on (alpha-glucosidase (AG) activity was developed by using bismuth film modified glassy carbon electrode (BiFE). AG enzyme was immobilized on the BiFE by means of gelatin membrane and the activity ... -
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 ... -
Examination of performance of glassy carbon paste electrode modified with gold nanoparticle and xanthine oxidase for xanthine and hypoxanthine detection
Çubukçu, Meliha; Timur, Suna; Anık, Ülkü (Elsevier, 2007)A composite electrode was prepared by modifying glassy carbon microparticles with gold nanoparticles (Au-nps) and xanthine oxidase enzyme (XOD) for xanthine (X) and hypoxanthine (Hx) detection. After the optimization of ... -
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 ...
