Recent advances in nanomaterial design and synthesis has resulted in robust sensing systems that display superior analytical performance. The use of nanomaterials within sensors has accelerated new routes and opportunities for the detection of analytes or target molecules. Among others, carbon-based sensors have reported biocompatibility, better sensitivity, better selectivity and lower limits of detection to reveal a wide range of organic and inorganic molecules. Carbon nanomaterials are among the most extensively studied materials because of their unique properties spanning from the high specific surface area, high carrier mobility, high electrical conductivity, flexibility, and optical transparency fostering their use in sensing applications. In this paper, a comprehensive review has been made to cover recent developments in the field of carbon-based nanomaterials for sensing applications. The review describes nanomaterials like fullerenes, carbon onions, carbon quantum dots, nanodiamonds, carbon nanotubes, and graphene. Synthesis of these nanostructures has been discussed along with their functionalization methods. The recent application of all these nanomaterials in sensing applications has been highlighted for the principal applicative field and the future prospects and possibilities have been outlined.

“…As a result, seeking suitable carriers for NiCo 2 O 4 is conducive for higher catalytic activity. For example, graphene oxide (GO) is a prominent candidate, which is famous for its rich carbon sources, ecology friendly properties, large theoretical surface areas, and unique electronic properties. − Studies have shown that recyclable sponges modified with GO and molybdenum sulfide (MoS 2 ) nanoflowers exposed more active sites of Mo 4+ on the surface than pristine MoS 2 . These 3D materials can reach a notable removal rate (97.87%) of sulfadiazine (SDZ, 140L 120.0 mg/L) after 16 days, which provided sponges the possibility to be a suitable carrier in AOPs .…”

Advanced oxidation processes (AOPs) based on peroxymonosulfate (PMS) have been effective techniques for wastewater treatment. However, the recovery of powder catalysts and their granulation are limiting the application of heterogeneous AOPs technology. To tackle these issues, recoverable graphene oxide-based three-dimensional (3D) cobalt−nickel bimetallic sponges (SCNGs) were synthesized via a simple dipping process. Thermogravimetric analysis confirmed that the bimetal content of SCNGs was only 7.7%. The SCNGs/PMS system was proved to be greatly effective to treat various organic pollutants, achieving over 71% and 94% of degradation efficiency for phenolic substances (phenol and 4-chlorophenol) and antibiotics (tetracycline and sulfadiazine) in 5 min over a wide initial pH range of 4.0−9.0, respectively. The correlative quenching experiments and electronic paramagnetic resonance tests verified the existence of multiple reactive oxygen species ( 1 O 2 , SO 4•− , HO • , and O 2 •− ), whereas 1 O 2 that originated from PMS self-decomposition and O 2•− conversion played the most important role in the degradation processes. Overall, this study provides a prospect for the industrial application of 3D bimetallic materials based on PMS activation in wastewater treatment.
