The application of silicalite for improvement of working characteristics of conductometric enzyme biosensors for determination of sucrose was studied in this research. Biosensors based on different types of silicalite-modified electrodes were studied and compared according to their analytical characteristics. Polyethylenimine/glutaraldehyde/silicalite-modified biosensors showed higher sensitivity compared with others type of biosensors. Moreover, the polyethylenimine/glutaraldehyde/silicalite sucrose biosensors were characterized by high selectivity and signal reproducibility (relative standard deviation (RSD) = 2.78% for glucose measurements and RSD = 3.2% for sucrose measurements). Proposed biosensors were used for determination of sucrose in different samples of beverages. The obtained results had good correlation with results obtained by HPLC. Thus, polyethylenimine/glutaraldehyde/ silicalite-modified biosensors have shown perspective characteristics for the development of effective conductometric enzyme biosensors.

Development of Silicalite/Glucose Oxidase-Based Biosensor and Its Application for Glucose Determination in Juices and Nectars
Dudchenko, Oleksandr Ye; Pyeshkova, Viktoriya M.; Soldatkin, Oleksandr O.; Akata Kurç, Burcu; Kasap, Berna O.; Soldatkin, Alexey P.; Dzyadevych, Sergei V. (2016-02-03)
The application of silicalite for improvement of enzyme adsorption on new stainless steel electrodes is reported. Glucose oxidase (GOx) was immobilized by two methods: cross-linking by glutaraldehyde (GOx-GA) and cross-linking by glutaraldehyde along with GOx adsorption on silicalite-modified electrode (SME) (GOx-SME-GA). The GOx-SME-GA biosensors were characterized by a four-to fivefold higher sensitivity than GOx-GA biosensor. It was concluded that silicalite together with GA sufficiently enhances enzyme ...
Application of enzyme/zeolite sensor for urea analysis in serum
Soldatkin, O. O.; Kucherenko, I. S.; Marchenko, S. V.; Kasap, B. Ozansoy; Akata Kurç, Burcu; Soldatkin, A. P.; Dzyadevych, S. V. (2014-09-01)
Urea biosensor based on zeolite-adsorbed urease was applied for analysis of blood serum samples. It should be noted, that this biosensor has a number of advantages, such as simple and fast performance, the absence of toxic compounds during biosensor preparation, high reproducibility and repeatability (RSD = 9% and 4%, respectively). The linear range of urea determination by using the biosensor was 0.003-0.75 mM, and the limit of urea detection was 3 mu M. The method of standard addition was used for analysi...
Effect of different modifications of BEA-zeolites on operational characteristics of conductometric biosensor
Kucherenko, I. S.; Soldatkin, O. O.; Soy, E.; Kirdeciler, K.; ÖZTÜRK, SEMRA; Akata Kurç, Burcu; Jaffrezic-Renault, N.; Soldatkin, A. P.; Dzyadevych, S. V. (2012-08-01)
Effect of different modifications of zeolite Na+-BEA on working characteristics of urease-based conductometric biosensor was studied. As the biosensor sensitive elements were used bioselective membranes based on urease and various zeolites immobilised with bovine serum albumin on the surface of conductometric transducers. Influence of zeolites on sensitivity of urea biosensor was investigated as well as reproducibility of biosensor signal and reproducibility of activity of the bioselective element after dif...
NANOSIZED ZEOLITES AS A PERSPECTIVE MATERIAL FOR DEVELOPMENT OF ELECTROCHEMICAL ENZYME BIOSENSORS
Kucherenko, Ivan; Soldatkin, Oleksandr; Saiapina, Olga; Soy, Esin; Ozansoy, Berna; Kirdeciler, Salih Kaan; Öztürk, Seçkin; Akata Kurç, Burcu; Dzyadevych, Sergei (null; 2015-09-15)
In this work, the method of enzyme adsorption on different zeolites and mesoporous silica spheres (MSS) was investigated for the creation of conductometric biosensors. The conductometric transducers consisted of gold interdigitated electrodes were placed on the ceramic support. The transducers were modified with zeolites and MSS, and then the enzymes were adsorbed on the transducer surface. Different methods of zeolite attachment to the transducer surface were used; drop coating with heating to 200°C turned...
Construction of an acetylcholinesterase-choline oxidase biosensor for aldicarb determination
Kok, FN; Bozoglu, F; Hasırcı, Vasıf Nejat (2002-06-01)
In this study, acetylcholinesterase and choline oxidase were co-immobilized on poly(2-hydroxyethyl methacrylate) membranes and the change in oxygen consumption upon aldicarb introduction was measured. Immobilization of the enzymes was achieved either by entrapment or by surface attachment via a hybrid immobilization method including epichlorohydrin and Cibacron Blue F36A activation. Immobilized enzymes had a long-storage stability (only 15% activity decrease in 2 months in wet storage and no activity loss i...
