“…The MXene’s Raman spectra also exhibited peaks associated with titanium oxides (rutile phase) at 382 and 617 cm –1 . The rGO-PDDA spectra exhibited signature D- and G-bands (1324 and 1590 cm –1 , respectively) with an intensity ratio of 1.15 that was higher than that of GO itself ( I D / I G : 0.84, Figure S8), which was attributed to defects that occurred during the reduction process . In the rGO-PDDA/MXene multilayer, signatures of both materials were observed.…”

As the demand for wearable electronic devices increases, interest in small, light, and deformable energy storage devices follows suit. Among these devices, wire-shaped supercapacitors (WSCs) are considered key components of wearable technology due to their geometric similarity to woven fiber. One potential method for creating WSC devices is the layer-by-layer (LbL) assembly technique, which is a "bottom-up" method for electrode fabrication. WSCs require conformal and adhesive coatings of the functional material to the wire-shaped substrate, which is difficult to obtain with other processing techniques such as vacuum filtration or spray-coating. However, the LbL assembly technique produces conformal and robust coatings that can be deposited onto a variety of substrates and shapes, including wires. In this study, we report WSCs made using the LbL assembly of alternating layers of positively charged reduced graphene oxide functionalized with poly-(diallyldimethylammonium chloride) and negatively charged Ti 3 C 2 T x MXene nanosheets conformally deposited on activated carbon yarns. In this construct, the added LbL film enhances capacitance, energy density, and power density by 240, 227, and 109%, respectively, relative to the uncoated activated carbon yarn, yielding high specific and volumetric capacitances (237 F g −1 , 2193 F cm −3 ). In addition, the WSC possesses good mechanical stability, retaining 90% of its initial capacity after 200 bending cycles. This study demonstrates that LbL coatings on carbon yarns are promising as linear energy storage devices for fibrous electronics.

Early diagnosis of the disease can appreciably improve the survival rate or facilitate effective treatment with different modalities. In the field of disease diagnosis; nanomaterial-based biosensing and bioimaging techniques are lifting hopes for point-of-care cancer diagnosis with ultra-high selectivity and sensitivity. Graphene, including twodimensional (2D) graphene films, three-dimensional (3D) graphene architectures, Graphene dots, and graphene hybrids (GHs) nanostructures have attracted the researcher`s interest in the field of biosensing and bioimaging owing to their properties. Versatile platforms of graphene nanomaterials make it as germane to detect the biomarkers at the early stage of cancer. This review selectively summarizes the recent progress in using graphene-based nanomaterials for detecting lung cancer biomarkers. Explicitly, graphene-electrochemical biosensors, which are classified according to sensing mechanisms and targets (CEA, NSE, hTERT, CYFRA21-1), are thoroughly discussed. Herewith, future scopes and challenges with other matrices, nano-scaffolds have also discoursed in the conclusion and future perspective.

“…Carbon nanomaterials such as graphene, graphene oxide, carbon nanotubes (CNTs), and acid functionalized CNTs have been studied for their potential toxicity and their cytotoxic mechanisms in cells for further biomedical applications. It was found that neat graphene was toxic when treated with a Raw 264.7 cell by inducing the production of reactive oxygen species and apoptosis [21] and the nanocomposite of metal and graphene can be applied as an electrochemical sensor, using excellent thermal conductivity and electric conductivity [22]. Graphene oxide is involved in the release of lactate dehydrogenase (LDH) released from dead or damaged cells by apoptosis or necrosis and causing toxicity, due to the accumulation of autophagosome [23].…”

Nanodiamonds are emerging as new nanoscale materials because of their chemical stability, excellent crystallinity, and unique optical properties. In this study, the structure of nanodiamonds was engineered to produce carbon nano-onion particles (CNOs) with multiple layers. Following a series of physicochemical characterizations of the CNOs, various evaluations for biological responses were conducted for potential biotechnological applications of the CNOs. The possibility of biological applications was first confirmed by assessment of toxicity to animal cells, evaluation of hemolysis reactions, and evaluation of reactive oxygen species. In addition, human immune cells were evaluated for any possible induction of an immune response by CNOs. Finally, the toxicity of CNOs to Escherichia coli present in the human colon was evaluated. CNOs have the chemical and physical properties to be a unique variety of carbon nanomaterials, and their toxicity to animal and human cells is sufficiently low that their biotechnological applications in the future are expected.
