From their foundational role in electronics to their pivotal contributions in the structural domain, carbon nanotubes (CNTs) exemplify a revolutionary nanomaterial with broad applications. The chemical inertness of the CNT surface is a primary limitation that restricts the full utilization of CNTs for mass use in several applications. Herein, works performed on the development of surface‐modified CNTs known as periodically patterned structures are focused. Different structures including shish kebab, nanofiber, nanoflower, and cheetah skin CNT have been studied. Periodic patterning on CNTs offers a chance to improve the nanotube's surface properties and roughness, facilitating better interaction with a matrix. Additionally, the fully controllable processing procedure opens significant opportunities for additional modification and attachment of phases onto specific areas of periodically patterned CNTs. The periodic patterning aspect holds promise for the mass production of surface‐modified CNTs, enhancing their surface multifunctionality. This advancement has the potential to cater to a diverse array of applications, offering improved surface functionality in a mass‐production setting.

“…For example, in the case of Rhodamine B, the lethal concentration of 10% (LC10) for crustaceans is 18 mg/L [ 21 ]; hence, the sensor should demonstrate low-level detection below this value. In this case, CNTs can improve the performance of the sensors being developed according to their unique interaction with chemical compounds [ 22 ].…”

The present study aimed to improve the optical sensing performance of tapered optical fiber sensors toward aqueous Rhodamine B solution of different concentrations by applying single-walled carbon nanotubes (SWCNTs). The functional coating was formed on the surface of the tapered optical fiber sensor using an aerosol layer-by-layer deposition method. Before deposition, the SWCNTs were processed with multistage liquid-phase treatment in order to form a stable dispersion. The effect of SWCNT treatment was investigated through Raman spectroscopy. The deposition of 220 layers caused a reduction of up to 60% of the initial optical power of radiation propagating through the optical fiber core. The optical fiber sensor coated with SWCNTs demonstrated significantly higher sensitivity compared to a non-coated sensor in the range of 2–32 mg/L of Rhodamine B concentration in an aqueous solution. The experimental results demonstrated that the sensitivity was increased 10 times from 32 (mg/L)−1, for the non-coated sensor, up to 317 (mg/L)−1 after SWCNT coating deposition. Moreover, the SWCNT-coated sensor demonstrated high repeatability that allowed for the evaluation of the concentration regardless of the previously analyzed dye concentration.

“…So far, scientists have done a lot of research on this, and many materials with excellent electrochemical properties have been used to improve the performance of sensors ( Abbas and Amin, 2022 ; Shao et al, 2022 ). Among them, the carbon nanotube is treated as an ideal material for the chemical modified electrode owing to excellent performance ( Zhang and Du, 2020 ; Billing, 2021 ). Carbon nanotubes are composed of pure carbon atoms that interact through strong sp 2 carbon-carbon bonds.…”

via simple hydrothermal method, CeO2 was in-situ grown onto the CNTs to form CeO2/CNTs nanocomposites were synthesized with cerium nitrate as Ce resource. The morphology and structure were characterized by transmission electron microscopy and X-ray diffraction. The characterizations reveal that CeO2 nanoparticles are uniformly dispersed onto the surface of the pre-acidified CNTs. The electrochemical property of the synthesized nanocomposite was investigated in 0.1 M KCl electrolyte containing 2 mM [Fe(CN)6]3-/4-. The nanocomposites were employed to fabricate electrochemical sensor for phenol detection. The linear range for phenol detection measured by the differential pulse voltammetry method is 1–500 μM. The sensor also exhibits good selectivity, reproducibility and stability. When applied for the river and tap water analysis, it shows good recovery rate.
