“…Moreover, FTIR analysis was carried out to thoroughly investigate the surface groups of the CNOs. As shown in Figure C, the peaks at 1604, 1796, 2859, and 3442 cm –1 confirmed the presence of the CC, CO, C–H, and O–H stretching vibrations, respectively. , These were consistent with previously reported results. , Further, the morphology of LIG and LI(G-POM) was characterized by SEM. In Figure D, LIG is observed to exhibit a 3D and porous layer shape structure after the high-energy laser radiation.…”

An electrochemiluminescent (ECL)–photoacoustic (PA) dual-signal output biosensor based on the modular optimization and wireless nature of a bipolar electrode (BPE) was constructed. To further simplify the detection process, the BPE structure was designed as three separate units: anode ECL collection, cathode catalytic amplification, and intermediate functional sensing units. Specifically, the anode unit was placed with Eosin Yellow, a cheap and effective ECL reagent, and the cathode unit was a laser-induced polyoxometalate–graphene electrode, which was helpful to enhance the anode ECL signal. The intermediate functional sensing unit consisted of a temperature-sensitive conductive film. Further, using a carbon nano-onion nanocomposite with excellent absorption performance in the near-infrared region as a signal tag not only leads to changes in the electrical conductivity of the film through heat transfer and thus affects the ECL signal but also produces a strong PA response. With this design, PA and ECL signals can be output simultaneously. This work not only realizes multiple modularization processes in the design of sensors but also implements the diversification of signal output modes, which will enrich the joint research field of ECL detection technology and other new detection methods.

“…3a, we suggest that the excitation-wavelength-dependent emission at 300–400 nm with the PL centre at approximately 450 nm can be attributed to the variable surface state of the CNOs, whereas the excitation-wavelength independent emission at 280–300 nm was ascribed to exciton recombination through π–π* transitions. 33,34 As exemplified by the images of CNO dispersed in ethanol under ambient light and UV light in Fig. 3c, a bright blue emission was clearly observed.…”

For field-like environmental gas monitoring and noninvasive illness diagnostics, effective sensing materials with exceptional sensing capabilities of sensitive, quick detection of volatile organic compounds (VOCs) are required. Carbon-based nanomaterials (CNMs), like CNTs, graphene, carbon dots (Cdots), and others, have recently drawn a lot of interest for their future application as an elevated-performance sensor for the detection of VOCs. CNMs have a greater potential for developing selective sensors that target VOCs due to their tunable chemical and surface properties. Additionally, the mechanical versatility of CNMs enables the development of novel gas sensors and places them ahead of other sensing materials for wearable applications. An overview of the latest advancements in the study of CNM-based sensors is given in this comprehensive organized review.
