“…The growth of CNTs was carried out on iron catalytic nanoparticles. The nanoparticles were deposited in microwave plasma torch with dual-flow nozzle electrode according to the technique described in [20,21]. Si/SiO2 substrate was placed in a holder for 4 samples with 4 × 4 mm deposition area for each sample.…”

The role of plasma functionalization of multi-walled carbon nanotubes (MWCNTs) for room temperature ammonia gas sensors was investigated. Plasma functionalization of MWCNTs with maleic anhydride was carried out with various durations. Active material of gas sensor was investigated by scanning electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. It has been shown that formation of functional groups on the surface of carbon nanotubes led to the increase in ammonia sensor response by 2-4 times. The increase of functionalization duration induces the rise of O:C from 0.28 to 0.335, increase of sensor resistance, and the distortion of shape of I-V curves.

“…It is important to detect NH 3 and NO 2 because they are harmful to human health and the environment [ 35 ]. Various CNT-based sensors have emerged to monitor these two toxic gases [ 36 , 37 , 38 , 39 , 40 , 41 , 42 ]. Valentini et al [ 43 ] demonstrated a chemiresistive gas sensor for sensing NO 2 .…”

The development of simple and low-cost chemical sensors is critically important for improving human life. Many types of chemical sensors have been developed. Among them, the chemiresistive sensors receive particular attention because of their simple structure, the ease of high precise measurement and the low cost. This review mainly focuses on carbon nanotube (CNT)-based chemiresistive sensors. We first describe the properties of CNTs and the structure of CNT chemiresistive sensors. Next, the sensing mechanism and the performance parameters of the sensors are discussed. Then, we detail the status of the CNT chemiresistive sensors for detection of different analytes. Lastly, we put forward the remaining challenges for CNT chemiresistive sensors and outlook the possible opportunity for CNT chemiresistive sensors in the future.

“…Sensing is an important area in modern society, because the use of sensors is a widespread reality, for example in the gas emission control industry, household security, automotive emission control, environmental monitoring and health care diagnosis. Most investigations have focused on detecting oxygen (O2) [9,10], ozone (O3) [11], carbon monoxide (CO) [12,13], carbon dioxide (CO2) [14], ammonia (N3) [15], sulfur dioxide (SO2) [15] and hydrogen (H2) [16,17]. Other organic gases such as ethanol [18], benzene [19], isopropanol [20], acetone [21,22] and methanol [23] have also called attention to be detected.…”

Carbon Nanostructures as a Multi-Functional Platform for Sensing Applications

The various forms of carbon nanostructures are providing extraordinary new opportunities that can revolutionize the way gas sensors, electrochemical sensors and biosensors are engineered. The great potential of carbon nanostructures as a sensing platform is exciting due to their unique electrical and chemical properties, highly scalable, biocompatible and particularly interesting due to the almost infinite possibility of functionalization with a wide variety of inorganic nanostructured materials and biomolecules. This opens a whole new pallet of specificity into sensors that can be extremely sensitive, durable and that can be incorporated into the ongoing new generation of wearable technology. Within this context, carbon-based nanostructures are amongst the most promising structures to be incorporated in a multi-functional platform for sensing. The present review discusses the various 1D, 2D and 3D carbon nanostructure forms incorporated into different sensor types as well as the novel functionalization approaches that allow such multi-functionality.
