“…Hwang et al 49 introduced an innovative one-pot synthesis approach for the production of reduced-graphene oxide quantum dots (rGOQDs) in a perfluorotributylamine (PFTBA) solution. This method not only eliminated the requirement for toxic materials but also prevented the formation of undesirable functional groups such as epoxy, carbonyl, and carboxyl.…”

“…The environment-friendly graphene grown at 600 °C showed the highest conductivity value of 1219 S/m. A one-pot preparation method was reported by Hwang et al [ 45 ] for the synthesis of eco-friendly reduced graphene oxide quantum dots. They used perfluorotributylamine solution consisting of three butyl fluoride groups connected to an amine center able to produce reduced-graphene oxide quantum dots at 160 °C from reduced-graphene oxide precursor.…”

At present, analytical lab-on-chip devices find their usage in different facets of chemical analysis, biological analysis, point of care analysis, biosensors, etc. In addition, graphene has already established itself as an essential component of advanced lab-on-chip devices. Graphene-based lab-on-chip devices have achieved appreciable admiration because of their peerless performance in comparison to others. However, to accomplish a sustainable future, a device must undergo “green screening” to check its environmental compatibility. Thus, extensive research is carried out globally to make the graphene-based lab-on-chip green, though it is yet to be achieved. Nevertheless, as a ray of hope, there are few existing strategies that can be stitched together for feasible fabrication of environment-friendly green graphene-based analytical lab-on-chip, and those prospective pathways are reviewed in this paper.

“…Two-dimensional (2D) materials have been widely utilized for the fabrication of various colorimetric sensors and biosensors due to their special structure and properties, including their 2D layered structure, good conductivity, high mechanical stability, and facile functionalization [18][19][20]. First, the higher specific surface area properties of 2D materials can provide more active sites for binding analytes, which can improve the sensitivity of the fabricated colorimetric biosensors.…”

Two-dimensional (2D) materials such as graphene, graphene oxide, transition metal oxide, MXene and others have shown high potential for the design and fabrication of various sensors and biosensors due to their 2D layered structure and unique properties. Compared to traditional fluorescent, electrochemical, and electrical biosensors, colorimetric biosensors exhibit several advantages including naked-eye determination, low cost, quick response, and easy fabrication. In this review, we present recent advances in the design, fabrication, and applications of 2D material-based high-performance colorimetric biosensors. Potential colorimetric sensing mechanisms and optimal material selection as well as sensor fabrication are introduced in brief. In addition, colorimetric biosensors based on different 2D materials such as graphene, transition metal dichalcogenide/oxide, MXenes, metal–organic frameworks, and metal nanoplates for the sensitive detection of DNA, proteins, viruses, small molecules, metallic ions, and others are presented and discussed in detail. This work will be helpful for readers to understand the knowledge of 2D material modification, nanozymes, and the synthesis of hybrid materials; meanwhile, it could be valuable to promote the design, fabrication, and applications of 2D material-based sensors and biosensors in quick bioanalysis and disease diagnostics.
