“…In order to the fabrication of Cu@PCR electrode, firstly, conducting polymer matrix has been prepared on the bare graphite electrode. For this reason, the bare graphite electrode has been polished and washed thoroughly with distilled water [30]. The electrochemical polymerization of the CR monomer has been performed by the CV technique, which was depicted the reversibility of electron transfer during the polymerization.…”

“…Another important factor that limits the applicability of the prepared sensor platform in various samples is the presence of compounds that can interfere. Phenolic compounds, ethanol, ascorbic acid and other oxidizable compounds often coexist with glucose in real samples such as beverages and possibly interfere with the detection of glucose [30].…”

In this work, rapid, sensitive, practical, and economical strategy for non‐enzymatic glucose sensor has been reported based on a modification of copper nanoparticles upon conducting polymer with high surface area (Cu@PCR). Firstly, PCR conducting polymer electrode (PCR) has been successfully fabricated by electrochemical polymerization of a specially synthesized and characterized star‐shaped carbazole derivative. Then copper nanoparticles have been successfully electrodeposited on the PCR as a practical method with cyclic voltammetry. The morphologies of the synthesized materials have been characterized by scanning electron microscopy (SEM) and energy‐dispersive spectroscopy (EDS) measurements. The Cu@PCR sensor platform has been displayed a synergistic effect of high catalytical properties of copper nanoparticles and high electroactive properties of PCR towards the glucose oxidation in alkaline medium. The Cu@PCR sensor platform has shown high sensitivity of 847 μAmM−1cm−2, good stability (10 weeks), a low detection limit of 0.043 μM, and a fast response of 3 s for the non‐enzymatic electrochemical detection of glucose. This organic−inorganic hybrid composite sensor is a promising candidate for the fabrication of a highly sensitive and rapid glucose‐sensing with the simple preparation procedure and use of a low‐cost precursor.

Gelişen teknolojiyle birlikte polimerik kompozit malzemeler üstün elektriksel özellikleri sebebiyle dikkat çekmektedir. Günümüzde yüksek yük yoğunluğuna, türevlendirilebilir fonksiyonel gruplara sahip ve elektron transferine olanak sağlayan, düşük maliyetli karbon nanomateryallerin polimerik malzemeler ile birleştirilerek, yeni kompozit malzemelerin üretimi, bu malzemelerin üstün elektriksel ve mekanik özelliklerinden dolayı tercih edilmektedir. Bu sebeple, bu çalışmada, indirgenmiş grafen oksit (rGO) ile modifiye edilmiş indiyum kalay oksit (ITO) kaplı çalışma elektrodu üzerine (E)-4-(2,5-di(tiyofen-2-yl)-1H-pirol-1-yl)-N-(piren-1-ylmetilen) anilinin (PMA) elektrokimyasal yöntemle kaplanmasıyla elde edilen kompozit malzemenin elektrokimyasal özellikleri incelenmiştir. PMA, piren-4-karbaldehit ve 4-(2,5-di(tiyofen-2-yl)-1H-pirol-1-yl)anilinin, kondenzasyon reaksiyonu sonucu başarılı bir şekilde sentezlenmiş ve karakterizasyonu 1 H-NMR ile gerçekleştirilmiştir. Elde edilen rGO/pPMA kompozitinin, elektrokimyasal teknikler kullanılarak stabilitesi, yük yoğunluğu, spektroelektrokimyasal teknikler kullanılarak ise optik özellikleri analiz edilmiştir. Elde edilen sonuçlar değerlendirildiğinde, üretilen nanokarbon (NCM) ile desteklenmiş kompozit malzemenin %99'luk mükemmel bir elektrokimyasal kararlılığa ve % 42 gibi akıllı malzemelerde kullanılabilecek yüksek bir optik geçirgenliğe sahip olduğu gözlenmiştir. Gözlenen mükemmel stabilite ve yüksek optik geçirgenlik, üretilen kompozit malzemenin teknolojik uygulamalarda kullanımı için ümit vaat etmektedir.

An amperometric biosensor for glucose determination was developed using a carbon paste electrode (CPE) modified with cellulose acetate (CA)/glucose oxidase (GOx) bilayer membrane through the electrostatic interaction between them. The CA membrane was used as matrix for enzyme immobilization via microencapsulation technique, is enzyme placed between two membranes. CA/GOx membrane was attached to CPE surface containing ferrocene (Fc). By using proposed amperometric biosensor, glucose concentration was determined as well as its characteristic. The modified Fc–graphite electrode with CA/GOx bilayer membrane for glucose had optimum measurement conditions at work emf of 874 mV, CA concentration of 10% and amount Fc of 0.021 mg. The biosensor showed good performance at glucose concentration range of 0.05–3 mM and limit of detection was 0.024 mM. Proposed biosensor has good reproducibility with relative standard deviation (RSD) was less than 5% up to 7 times use (in the defined condition 4 ˚C). Glucose measurement result in human serum of diabetes mellitus patients showed conformity with result of reference method, MediSense Optium glucose test kit.
