“…However, the lacking of the structure engineering would limit the exploitative peculiarity and application of FG. [54,65,71,[93][94][95]141,149,184,220] Therefore, the elaborate structure engineering for customizing the structure and performances of FG is the most important research point in the past several years, which is also the urgent and significant avenue in its future development. The fluorine content is the simplest and fundamental character of FG, which has been introduced in the above intrinsic properties section.…”

“…[70] Another advantage of hydrogenating the surface of graphene is the good level of hydrophilicity that results, which can be exploited for biological application. Son et al (2019) fabricated a novel hydro fluorinated graphene by indirectly exposing xenon difluoride and hydrogenated graphene. [71] The surface properties of these materials can be tailored by controlling the concentration of hydro fluorinated graphene.…”

drug delivery, bioimaging probes, antibacterial agents, and tissue engineering. [2] The advantage of GBMs over other nanomaterials (NMs) in biomedical application is their high specific surface area which allows high density functionalization and drug loading on both sides of the planar structure. [3] The π-conjugated system offers high capacity for GBMs to interact with various organic compounds with aromatic structures through π-π stacking during fabrication of graphene composites or for immobilization of biomolecules such as nucleic acids, peptides, antibodies, or other therapeutic substances. [4] The same properties may also raise concerns regarding the potential risk that GBMs may cause to human health through binding of key signaling molecules for example. GBMs may interact with biomolecules, changing the structure of protein or DNA or induce oxidative damage, and so on. [5] Therefore, prior to the widespread use of GBMs, it is imperative to evaluate their potential risk to environmental and human health and to establish a proactive approach for the safe design of these materials.In a recent review article, Fadeel et al. comprehensively examined the literature on the effects of GBMs on human health and the environment and gave an overview of the state-of-the-art of safety assessment of GBMs, highlighting the importance of The increasing exploitation of graphene-based materials (GBMs) is driven by their unique properties and structures, which ignite the imagination of scientists and engineers. At the same time, the very properties that make them so useful for applications lead to growing concerns regarding their potential impacts on human health and the environment. Since GBMs are inert to reaction, various attempts of surface functionalization are made to make them reactive. Herein, surface functionalization of GBMs, including those intentionally designed for specific applications, as well as those unintentionally acquired (e.g., protein corona formation) from the environment and biota, are reviewed through the lenses of nanotoxicity and design of safe materials (safe-by-design). Uptake and toxicity of functionalized GBMs and the underlying mechanisms are discussed and linked with the surface functionalization. Computational tools that can predict the interaction of GBMs behavior with their toxicity are discussed. A concise framing of current knowledge and key features of GBMs to be controlled for safe and sustainable applications are provided for the community.

“…Then, when the system is dipped in water, the water interacts strongly with both the substrate and the graphene to act as a wedge, easily and cleanly separating the graphene and the substrate. In addition, the hydrophobicity of the hydrogenated graphene [74][75][76][77] likely stabilizes the graphene on the water surface without the need for a polymer support. The hydrogen functionality acts akin to a surfactant, mimicking a technique that has been previously employed in aqueous exfoliation of bulk graphite [78].…”

Graphene, synthesized either epitaxially on silicon carbide or via chemical vapor deposition (CVD) on a transition metal, is gathering an increasing amount of interest from industrial and commercial ventures due to its remarkable electronic, mechanical, and thermal properties, as well as the ease with which it can be incorporated into devices. To exploit these superlative properties, it is generally necessary to transfer graphene from its conductive growth substrate to a more appropriate target substrate. In this review, we analyze the literature describing graphene transfer methods developed over the last decade. We present a simple physical model of the adhesion of graphene to its substrate, and we use this model to organize the various graphene transfer techniques by how they tackle the problem of modulating the adhesion energy between graphene and its substrate. We consider the challenges inherent in both delamination of graphene from its original substrate as well as relamination of graphene onto its target substrate, and we show how our simple model can rationalize various transfer strategies to mitigate these challenges and overcome the introduction of impurities and defects into the graphene. Our analysis of graphene transfer strategies concludes with a suggestion of possible future directions for the field.
