“…Having experience working with CNTs to create nanocomposite materials, we can find areas of application of CNTs in electronics [28][29][30]. This study extends the exploration initiated in a previous study in the development of nanocomposite thin film structures utilizing poly-arylenephthalide matrices with single-walled carbon nanotubes (SWCNT) and graphene oxide fillers [31]. It builds upon the advancements in hybrid molecular systems reported elsewhere, particularly in the synthesis of hybrid molecules incorporating fullerene C60 and dithienylethenes for optically controlled organic field-effect transistors (OFETs) [32].…”

The simple scaling of silicon transistors no longer ensures the advantages of high energy efficiency, driving research into nanotechnologies beyond silicon. Specifically, digital circuits based on carbon nanotube (CNT) field-effect transistors promise significant advantages in energy efficiency. However, the inability to perfectly control internal nanoscale defects and the variability of carbon nanotubes hinder the realization of very large-scale integrated systems. In this study, we investigated a novel method for fabricating transistors based on carbon nanotubes (CNTs) using epoxy mixtures, obtained the electrical properties of the transistors, and compared their microstructure and composition via the scanning electron microscopy. The carrier mobility on epoxy-based transistors was 28.87 cm²/V∙s, and the transistor switching frequency was 2.2 MHz. The samples exhibited electrical and physical stability over an extended period of time. The use of carbon nanotubes in epoxy resin as a conducting layer for transistors opens significant prospects in the field of electronics. The CNT-epoxy mixture technology allows for more flexible and rapid fabrication of thin-film transistors compared to classical methods. However, it is not appropriate to speak of a complete replacement; in this study, we present an alternative method for producing thin-film transistors, which may be of interest for specific purposes.

“…Therefore, components that increase electrical conductivity must be added to the sensor layer. Recently, nanomaterials have been used for these purposes, such as Au and Pt nanoparticles, single-walled and multi-walled carbon nanotubes, reduced graphene oxide (rGO) [13,17,27], etc. At the same time, rGO is also used as a convenient matrix for immobilizing various components when creating efficient sensor platforms based on composite materials and increasing the sensitivity and selectivity of voltammetric sensors due to its unique properties, such as high electrical conductivity, large specific surface area, mechanical strength, etc.…”

For the selective detection of the antibiotic lincomycin, we developed a voltammetric sensor based on a glassy carbon electrode modified with reduced graphene oxide and polyarylenephthalide containing diphenylenethio and diphenyleneoxide fragments in the main chain of the polymer in the 1:1 ratio with lincomycin molecular imprints obtained by phase inversion. Using FTIR spectroscopy, electrochemical impedance spectroscopy, cyclic and differential-pulse voltammetry, the electrochemical and analytical characteristics of the sensor were studied. The detection of lincomycin was carried out by differential pulse voltammetry. The linear concentration range was 2.5·10–7–5·10–4 M with a limit of detection of 6.8·10–8 M. It was shown that the presence of molecular imprints increases the sensitivity of the developed sensor in comparisons with a sensor with non-imprinted polymer by a factor of 3.05.
