“…In this context, graphene, mxene, CNTs, quantum dots, and fullerene can be discovered for the electronics nanosensor manufacturing industries. For instance, nantero has created the NRAM (nanotube-based/non-volatile random access memory) chip employing CNTs that may function as dynamic memory cells [ 191 ]. In 2006, IBM produced transistors based on CNTs [ 192 ].…”

In recent years, there has been immense advancement in the development of nanobiosensors as these are a fundamental need of the hour that act as a potential candidate integrated with point-of-care-testing for several applications, such as healthcare, the environment, energy harvesting, electronics, and the food industry. Nanomaterials have an important part in efficiently sensing bioreceptors such as cells, enzymes, and antibodies to develop biosensors with high selectivity, peculiarity, and sensibility. It is virtually impossible in science and technology to perform any application without nanomaterials. Nanomaterials are distinguished from fine particles used for numerous applications as a result of being unique in properties such as electrical, thermal, chemical, optical, mechanical, and physical. The combination of nanostructured materials and biosensors is generally known as nanobiosensor technology. These miniaturized nanobiosensors are revolutionizing the healthcare domain for sensing, monitoring, and diagnosing pathogens, viruses, and bacteria. However, the conventional approach is time-consuming, expensive, laborious, and requires sophisticated instruments with skilled operators. Further, automating and integrating is quite a challenging process. Thus, there is a considerable demand for the development of nanobiosensors that can be used along with the POCT module for testing real samples. Additionally, with the advent of nano/biotechnology and the impact on designing portable ultrasensitive devices, it can be stated that it is probably one of the most capable ways of overcoming the aforementioned problems concerning the cumulative requirement for the development of a rapid, economical, and highly sensible device for analyzing applications within biomedical diagnostics, energy harvesting, the environment, food and water, agriculture, and the pharmaceutical industry.

“…In our research, we used nanotubes to modify the electrode thanks to which the sensitivity of the determinations was increased compared to the procedure based on PbFE formed on classic glassy carbon electrodes and additionally the range of linearity has been increased. Carbon nanotubes, due to their extraordinary properties (mechanical, strength, electrical), have a wide area of application, and they also turned out to be a very valuable electrode material (Das et al 2022;Gupta et al 2019;Maheswaran and Shanmugavel 2022). Also in the case of voltammetric sensors, you can find the use of multiwall carbon nanotubes, such as carbon-nanotube-modified glassy carbon electrode (Baranowska and Bijak 2013;Kumar and Vicente-Beckett 2012), carbon-nanotube-modified carbon paste electrode (Deng et al 2008) as well as bismuth-modified carbon nanotube electrode (Hwang et al 2008;Stočes et al 2012) or copper film with carbon-nanotubes-modified electrode (Wasąg and Grabarczyk 2021).…”

We report the use of carbon nanotubes as a material for the preparation of an electrochemical sensor that acts as a substrate for film metal electrodes used in stripping voltammetry. The sensor is based on a mixture of multiwall carbon nanotubes, glassy carbon spherical powder, and epoxy resin. The properly selected composition of the sensor made it possible to obtain a new substrate, competitive in relation to glassy carbon, for creating film metal electrodes. In this work, the proposed new sensor was used to determine the trace amounts of Ti(IV) on the lead film electrode. Measurements were carried out with in situ mode in an acetate buffer by adsorption stripping voltammetry with the use of cupferron as a complexing agent. Linear response to Ti(IV) ions in the concentration range of 7 × 10–10–7 × 10–8 mol L−1 and the limit of detection (LODs) 2.4 × 10–10 were obtained, respectively. These promising results revealed that a mixture of carbon nanotubes, epoxy resin, and spherical glassy carbon powder used for the determination of titanium ions on PbFE might represent an important addition to existing electrochemical sensor technologies. The proposed procedure was successfully used as a new and powerful analytical tool for determination of Ti(IV) in horsetail extracts.

“…Among nanofillers, carbon nanotubes (CNTs) have attracted much attention due to their excellent electrical, mechanical and thermal properties [ 9 , 10 , 11 , 12 , 13 , 14 ]. In the last years, CNTs have become more affordable due to the development of large-scale production capacity and are thus used as fillers in polymers [ 15 ].…”

Mechanical Recycling of Ethylene-Vinyl Acetate/Carbon Nanotube Nanocomposites: Processing, Thermal, Rheological, Mechanical and Electrical Behavior

Recycling polymer/carbon nanotube (CNT) nanocomposites is not well common, despite a growing interest in using polymer/carbon nanotube (CNT) nanocomposites in industrial applications. In this study, the influence of mechanical recycling on the thermal, rheological, mechanical and electrical behavior of ethylene-vinyl acetate (EVA)/CNT nanocomposites is investigated. EVA/CNT nanocomposite with different amounts of CNTs (1, 3 and 5 wt.%) was subjected to mechanical grinding and reprocessing by injection molding in a close-loop up to three cycles, and the changes induced by mechanical recycling were monitored by Differential Scanning Calorimetry (DSC), capillary rheology, scanning electron microscopy (SEM), electrical resistance and tensile tests. It was found that the EVA/CNT nanocomposites did not exhibit significant changes in thermal and flow behavior due to mechanical recycling and reprocessing. The recycled EVA/CNT nanocomposites retain close to 75% of the original elastic modulus after three recycling cycles and about 80-90% in the tensile strength, depending on the CNT loading. The electrical conductivity of the recycled nanocomposites was about one order of magnitude lower as compared with the virgin nanocomposites, spanning the insulating to semi-conducting range (10−9 S/m–10−2 S/m) depending on the CNT loading. With proper control of the injection molding temperature and CNT loading, a balance between the mechanical and electrical properties of the recycled EVA nanocomposites can be reached, showing a potential to be used in practical applications.
