Spectroelectrochemistry (SEC) has been used for more than 50 years, but this set of techniques has not been widely used for quantitative analysis. For many years, no commercial instruments were available, which made very difficult to spread the use of SEC. Nowadays, only the creativity of the researchers is required to exploit the capabilities of SEC. This review is written with the aim of showing the potential of SEC, mainly for analytical chemistry. Here, we explain what SEC is, how analytical responses can be obtained, why these techniques are useful for sensors, with a brief description of its advantages in use, and, finally, we try to show the challenges that must be addressed in the next years. SEC can resolve interesting analytical problems using the high amount of data provided by this intrinsic trilinear technique. Given the quantitative analysis point of view of this review, the discussion of the SEC techniques is focused on UV/Vis absorption, photoluminescence and Raman SEC.

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.

“…Recently, for non‐enzymatic glucose detection, transition metals, metal oxides, carbon nanomaterials, or conducting polymers have been used as electrode material. Conducting polymers have found wide application in smart materials [7–12], sensors [13–18], and biomaterials [19,20] in recent years due to their superior electrical properties. Besides, conducting polymer provides a large surface area for the immobilization of metal nanoparticles because of its electrodeposits homogeneously, strongly adheres to the surface, and has chemical stability.…”

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.
