An isophorone‐based quaternary compound with two positively charged polymer chains has been synthesized to modify charge‐neutral graphene without affecting its unique intrinsic properties. A highly scalable dip and dry coating method is employed to coat the textile‐based substrates without subsequent post‐treatment. The resultant electronic textiles exhibit remarkably low sheet resistance ≈140 Ω sq−1) after 10 washing cycles, which is considerably better compared to any reported graphene‐based e‐textiles without post‐treatment. Graphene‐based nonwoven piezoresistive sensors developed for wearable e‐textiles use this approach to exhibit an impressive piezoresistive sensitivity in the low‐pressure range of 0 to 40 Pa and display good repeatability after washing cycles. Hence this novel modification strategy is envisaged to have strong potential for multifunctional applications in next‐generation graphene‐based wearable e‐textiles.

“…An alternative strategy to fabricate polymer-grafted carbon nanotubes involves the use of reversible addition–fragmentation chain transfer (RAFT) polymerization ( Hosseinzadeh et al, 2020 ; Eskandari et al, 2021 ). This approach offers precise control over the molecular mass of the polymer resulting in a narrow molecular mass distribution.…”

Carbon nanotube (CNT) nanocomposite scaffolds have emerged as highly promising frameworks for tissue engineering research. By leveraging their intrinsic electrical conductivity and valuable mechanical properties, CNTs are commonly dispersed into polymers to create robust, electrically conductive scaffolds that facilitate tissue regeneration and remodeling. This article explores the latest progress and challenges related to CNT dispersion, functionalization, and scaffold printing techniques, including electrospinning and 3D printing. Notably, these CNT scaffolds have demonstrated remarkable positive effects across various cell culture systems, stimulating neuronal growth, promoting cardiomyocyte maturation, and facilitating osteocyte differentiation. These encouraging results have sparked significant interest within the regenerative medicine field, including neural, cardiac, muscle, and bone regenerations. However, addressing the concern of CNT cytotoxicity in these scaffolds remains critical. Consequently, substantial efforts are focused on exploring strategies to minimize cytotoxicity associated with CNT-based scaffolds. Moreover, researchers have also explored the intriguing possibility of utilizing the natural cytotoxic properties of CNTs to selectively target cancer cells, opening up promising avenues for cancer therapy. More research should be conducted on cutting-edge applications of CNT-based scaffolds through phototherapy and electrothermal ablation. Unlike drug delivery systems, these novel methodologies can combine 3D additive manufacturing with the innate physical properties of CNT in response to electromagnetic stimuli to efficiently target localized tumors. Taken together, the unique properties of CNT-based nanocomposite scaffolds position them as promising candidates for revolutionary breakthroughs in both regenerative medicine and cancer treatment. Continued research and innovation in this area hold significant promise for improving healthcare outcomes.

“…Typically, there are two functionalization methods to modify CNTs, one is covalent, the other is non-covalent. Covalent modification of CNTs such as oxidation and carboxylation offers a stable platform for drug delivery, while non-covalent functionalization through Van der Waals interactions, π–π interactions, and hydrophobic interactions causes minimal damage to the surface of CNTs [ 36 ]. A lot of bioactive molecules such as antibodies and aptamers, various polymers and surfactants have been adopted to non-covalently functionalize CNTs to achieve increased biocompatibility and reduced toxicity (Fig.…”

Despite the exciting breakthroughs in medical technology, cancer still accounts for one of the principle triggers of death and conventional therapeutic modalities often fail to attain an effective cure. Recently, nanobiotechnology has made huge advancement in cancer therapy with gigantic application potential because of their ability in achieving precise and controlled drug release, elevating drug solubility and reducing adverse effects. Carbon nanotubes (CNTs), one of the most promising carbon-related nanomaterials, have already achieved much success in biomedical field. Due to their excellent optical property, thermal and electronic conductivity, easy functionalization ability and high drug loading capacity, CNTs can be applied in a multifunctional way for cancer treatment and diagnosis. In this review, we will give an overview of the recent progress of CNT-based drug delivery systems in cancer theranostics, which emphasizes their targetability to intracellular components of tumor cells and extracellular elements in tumor microenvironment. Moreover, a detailed introduction on how CNTs penetrate inside the tumor cells to reach their sites of action and achieve the therapeutic effects, as well as their diagnostic applications will be highlighted.
