“…When combined with GO, a significant enhancement in these optical properties may be observed due to the internal structural gaps of the nanomaterial. The addition of numerous oxygen-comprising functional groups into GO and quantum dots (GOQDs) [ 75 ], which are particles that comprise optical [ 76 ] and electrical qualities [ 77 ], has been found to play a key role in the photoluminescence of large wavelengths by modulating their band gaps. The photoluminescence of GOQDs has also exhibited quenching under distinct conditions and may therefore facilitate medical imaging applications and biosensor production [ 75 ].…”

This paper builds on the context and recent progress on the control, reproducibility, and limitations of using graphene and graphene-related materials (GRMs) in biomedical applications. The review describes the human hazard assessment of GRMs in in vitro and in vivo studies, highlights the composition–structure–activity relationships that cause toxicity for these substances, and identifies the key parameters that determine the activation of their biological effects. GRMs are designed to offer the advantage of facilitating unique biomedical applications that impact different techniques in medicine, especially in neuroscience. Due to the increasing utilization of GRMs, there is a need to comprehensively assess the potential impact of these materials on human health. Various outcomes associated with GRMs, including biocompatibility, biodegradability, beneficial effects on cell proliferation, differentiation rates, apoptosis, necrosis, autophagy, oxidative stress, physical destruction, DNA damage, and inflammatory responses, have led to an increasing interest in these regenerative nanostructured materials. Considering the existence of graphene-related nanomaterials with different physicochemical properties, the materials are expected to exhibit unique modes of interactions with biomolecules, cells, and tissues depending on their size, chemical composition, and hydrophil-to-hydrophobe ratio. Understanding such interactions is crucial from two perspectives, namely, from the perspectives of their toxicity and biological uses. The main aim of this study is to assess and tune the diverse properties that must be considered when planning biomedical applications. These properties include flexibility, transparency, surface chemistry (hydrophil–hydrophobe ratio), thermoelectrical conductibility, loading and release capacity, and biocompatibility.

“…GO as a biomolecular quencher has been well known and characterized. [9,10,11] Despite this exploitation of GO in predom-inately fluorescence quenching, bioluminescent quenching using GO is as a quencher has not been reported. Furthermore, the use of this bioluminescence-GO-based quenching technique for nucleic acid has not yet been explored.…”

Despite fluorescent quenching with graphene oxide (GO) having shown great success in various applications -bioluminescent quenching has not yet been demonstrated using GO as a quencher. To explore the ability of GO to quench bioluminescence, we used Gaussia luciferase (Gluc) as a donor and GO as a quencher and demonstrated its application in sensing of two target analytes, HIV-1 DNA and IFN-γ. We demonstrated that the incubation of Gluc conjugated HIV-1 and IFN-γ oligonucleotide probes with GO provided for monitoring of probe-target interactions based on bioluminescence meas-urement in a solution phase sensing system. The limits of detection obtained for IFN-γ and HIV-1 DNA detection were 17 nM and 7.59 nM, respectively. Both sensing systems showed selectivity toward the target analyte. The detection of IFN-γ in saliva matrix was demonstrated. The use of GO as a quencher provides for high sensitivity while maintaining the selectivity of designed probes to their respective targets. The use of GO as a quencher provides for an easy assay design and low cost, environmentally friendly reporter.

“…The study of such processes has been intensively carried out [20,21]. For example, fluorescence quenching of polymers by reduced graphene oxide [22], resonant energy transfer from a dye molecule to graphene [23], and interaction of graphene sheets with a dye using fluorescence quenching microscopy [24] have been reported. In addition, due to the growing attention to energy and environmental issues, many studies are focused on photocatalytic systems using graphene oxide and solar cells based on organic compounds, where dyes act as sensitizers.…”

The effect of graphene oxide on the spectral and luminescent properties of xanthene dyes was studied. During the interaction of graphene oxide (GO) with a cationic dye, aggregation of Rhodamine 6G occurs, which is expressed as an increase in the optical density of the short-wavelength shoulder in the absorption spectrum of the dye. GO sheets can act as adsorption centers for dye molecules due to the influence of the Coulomb and intermolecular forces between GO and Rhodamine 6G. This effect is practically not pronounced for anionic dyes. The quenching of the dye fluorescence intensity in the presence of GO was observed. Fluorescence quenching was equal to 2.4 times for Eosin, 5.8 times for Bengal rose, and 22.1 times for Rhodamine 6G. As shown by spectral-kinetic measurements, the fluorescence lifetime was also decreased in this case. Dye fluorescence quenching occurs through the process of electron transfer from the dye to GO. The results obtained can be used for the photodegradation of organic dyes by using of composite materials with graphene oxide.
