Here, a novel enzymatic biosensor was developed using multiwalled carbon nanotube including screen printed electrodes (MWCNT-SPE). Pyranose oxidase (PyOx) was immobilized on the electrode surface by way of gelatin membrane and then cross-linked using glutaraldehyde. Glucose was detected at -0.7 V (vs. Ag/AgCl) by watching consumed oxygen in enzymatic reaction after addition substrate. After optimization of pH and enzyme loading, the linearity was found in the range of 0.1-1.0 mM of glucose. After that, the effect of MCNT on the current was tested. Also the enzymatic biosensor including glucose oxidase instead of pyranose oxidase was prepared and the biosensor response followed for glucose. Furthermore, this system was tested for glucose analysis in soft drinks. Özet: Burada, çok duvarlı karbon nanotüp ile modifiye edilmiş şablonla baskılanmış elektrotları (MWCNT-SPE) kullanarak yeni bir enzimatik biyosensör geliştirilmiştir. Piranoz oksidaz (PyOx) jelatin membran vasıtasıyla elektrotların yüzeyine immobilize edilmiştir ve gluraldehid kullanarak çapraz bağlanma yapılmıştır. Glukoz; enzimatik reaksiyon sırasında kullanılan oksijen takip edilerek -0,7 V'da (Ag/AgCl'e karşı) belirlenmiştir. pH ve enzim miktarının optimizasyonundan sonra, glukoz tayini için doğrusal aralık 0,1-1,0 mM aralığı olarak bulunmuştur. Daha sonra, karbon nanotüplerin biyosensör cevabına etkisi test edilmiştir. Aynı zamanda piranoz oksidaz yerine glukoz oksidaz içeren enzimatik biyosensör hazırlanmıştır ve glukoz için biyosensör cevabı takip edilmiştir. Bunların dışında, içeceklerde glukoz analizi için sistem uygulanmıştır. Karbon Nanotüple Modifiye Edilmiş, Şablonla

Up to date, application of nanomaterials and nanotechnology has made great advances. Many novel nanomaterials with unique properties are increasingly being exploited to apply for biosensors, improving the property of biosensor and making them higher selectivity and sensitivity, less response time and lower detective limitation. Here we review some of the main advances in this field over the past few years, explore the application prospects, and discuss the issues, approaches, and challenges, with the amin of promting to develop nanomaterials-based biosensor nanotechnology and improving their application in disease diagnosis and biosafety examination.

“…Combination of the unique properties of carbon nanotubes into materials with high potential was caused their various applications. They improve dynamic range and reduce response time [20][21][22][23][24][25][26][27][28][29][30][31][32] . Zeolites are cr ystalline and hydrate aluminasilicates with tetrahedral structure that make up from an endless three-dimensional network from tetrahedral SiO 4 4-.and AlO 4 5-that are connected together with oxygen atoms.…”

A nanocomposite based on carbon paste electrode fabricated, by using zeolite as ion carrier .Functional multi-wall carbon nanotube was used for improvement of electrode response. The optimal composition of CPE was built from 65% graphite powder, 20 wt% paraffin oil, 5% ion carrier (zeolite), 10% MWCNTs. Electrode showed Nernstian response 19.88 (±0.2)mVdecade "1 in the measuring range 10 "7 -10 "2 mol L "1 and showed detection limit of 6.3×10 -7 M. The sensor was successfully used for potentiometric titration Cr 3+ with EDTA. The carbon paste electrode showed fast response time, good selectivity and applicable in the wide pH range of 3 -10.
