Graphene, a two-dimensional sheet of sp 2 hybridized carbon atoms, has shown to be the most fascinating and promising option among nanomaterials for a variety of applications, because of its unique structure and tunable physiochemical properties. It can be either in the pure form or in its modified derivatives that include graphene oxide (GO), reduced graphene oxide (rGO), graphene-metal nanoparticle composites, graphene-polymer hybrids, and graphene/organic structures that showed improved results while maintaining inherent properties of the material. These modified nanostructures have a variety of applications as catalysts, energy storage/conversion, antimicrobial, and water decontaminant. In the field of environmental science, graphene has been widely used for molecular sieving involving gas phase separation and organic waste removal from water, due to its biocompatibility, various functional groups, and accessible surface area. Modified graphene can also serve as a semiconductor that can increase the efficiency of the photocatalytic ecosystems that results in the inactivation of the microorganisms causing the organic chemicals to degrade.

“…The premise of the use of imidazolium‐based podands for the detection of nucleotides is described by Yoon and Kim [22] . Their development is quick [23,24] and gives nowadays birth to novel receptors which are sensitive, selective, and highly bioavailable [25–28] …”

“…nowadays birth to novel receptors which are sensitive, selective, and highly bioavailable. [25][26][27][28] Chen et al [26] have recently reported a new imidazoliumbased receptor (Figure 2) that is GMP-selective in the presence of GDP and GTP but also UMP (uridine monophosphate), TMP (thymine monophosphate) and AMP (adenine monophosphate) in a 100 % aqueous solution and inside of certain mammal living cells. The receptor is of tripodal type, built of three imidazolium rings, each of them bearing a fluorophore (1,8naphthyridine).…”

Luminescent Imidazolium Salts as Bright Multi‐Faceted Tools for Biology

2021

Light and cognate phenomena, e. g., luminescence are powerful tools endowed with great sensitivity to explore the infinitely small. Molecular salts, especially those based on imidazolium units, are granted with original properties and structural versatility. Associated with fluorophores, they constitute highly bioavailable platforms. Their interactions with negatively charged species and biological membranes as well as their controllable cytotoxicity imparted their applications as anion receptors, but also a promising potential as antibacterial and anticancer agents whose mechanism of action can be observed using luminescence, opening the possibility of theranostics (therapy and diagnosis). One of the other assets of imidazolium salts is their flexible amphipathic character which promotes their self‐organizations into liquid‐crystal mesophases and their ability to mimic lipids. Combining luminescence to these amphipathic properties opens new prospects, e. g., following gene or drug delivery inside cells. These salts, all‐in‐one, should lead to new tools for biologists, as well as active theranostic molecules.
