“…The rGO has the similar characteristics of the graphene nanosheets, i. e., the singular two‐dimensional structure formed by few layers of sp 2 carbon atoms, in a π‐conjugated system leading to high electron mobility and fast charge transfer allowing in the appearance of an electrocatalytic effect . The rGO act as a support for the immobilization of several species that can be used as platform for development of fuel cells , sensors , biosensors , and immunosensor .…”

The composite material of reduced graphene and Ru nanoparticles (rGO/RuNP) was obtained by electrochemical oxidation of ruthenium nanoparticles immobilised on the glassy carbon electrode (GCE) surface and used for simultaneous electroanalysis of drugs. There are many discussions in the scientific community about the decrease in therapeutic efficacy of contraceptives when associated with antibiotics. The antibiotic effect of the antagonist can increase the contraceptive excretion levels in urine, indicating a reduction in the body and thus a decrease in the desired effect. Using the DPV technique, it was possible to quantify ethinylestradiol (EE2) and amoxicillin (AMX) with a linear response range, 5.50x10−8 – 1.20x10−6 mol L−1, and LOD, 2.04 nmol L−1 and 1.63 nmol L−1, respectively. The results for the electrochemical behaviour of EE2 and AMX using GCE/rGO/RuNP were compared with GCE/rGO and GCE. The GCE/rGO/RuNP showed greater stability and separation anodic peak currents, suitable for the quantification of organic molecules in samples of environmental interest, as well as clinical and food samples.

“…GO is popular amongst nanomaterial hybrids including gold nanoparticles on polyoxometalate/reduced graphene oxide used as biosensors (35, 36). Nanomaterial-based electrochemical sensing of neurological drugs utilizing a hybrid of bimetallic Platinum-Palladium (Pt/Pd) nanoparticles on 2-thiolbenzimidazole functionalized reduced graphene oxide provided a significantly greater electrochemical surface area compared to other conventional electrodes used (32). Other GO based sensors have also been used for similar reasons (37–43).…”

A persistent theme in biomaterials research comprises of surface engineering and modification of bare metallic substrates for improved cellular response and biocompatibility. Graphene Oxide (GO), a derivative of graphene, has outstanding chemical and mechanical properties; its large surface to volume ratio, ease of surface modification and processing make GO an attractive coating material. GO-coatings have been extensively studied as biosensors. Further owing to its surface nano-architecture, GO-coated surfaces promote cell adhesion and growth, making it suitable for tissue engineering applications. The need to improve the long-term durability and therapeutic effectiveness of commercially available bare 316L stainless steel (SS) surfaces led us to adopt a polymer-free approach which is cost-effective and scalable. GO was immobilized on to 316L SS utilizing amide linkage, to generate a strongly adherent uniform coating with surface roughness. GO-coated 316 L SS surfaces showed increased hydrophilicity and biocompatibility with SHSY-5Y neuronal cells, which proliferated well and showed decreased reactive oxygen species (ROS) expression. In contrast, cells did not adhere to bare uncoated 316L SS meshes nor maintain viability when cultured in the vicinity of bare meshes. Therefore the combination of the improved surface properties and biocompatibility implies that GO-coating can be utilized to overcome pertinent limitations of bare metallic 316L SS implant surfaces, especially SS neural electrodes. Also, the procedure for making GO-based protective coatings can be applied to numerous other implants where the development of such protective films is necessary.

Fuel cells have important applications in recent decades due to high-energy demands, fossil fuel depletions and environmental pollution throughout world. A fuel cell is an electrochemical cell that converts a source fuel into an electrical current. It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte. In this study, preparation of Platinum nanoparticle (PtNPs)/boron nitride quantum dots (BNQDs)/6-methyl-2-(3-hydroxy-4-methoxybenzylidenamino)-benzothiazole (ILs) nanocomposite (PtNPs/BNQDs/ILs) has been made. Afterwards, using various equipment and methods, characterization has been carried out. These equipment and methods are as follows: Transmission Electron Microscope, Scanning Electron Microscope, X-Ray Photo Electron Spectroscopy, Energy-Dispersive X-Ray Spectroscopy and X-Ray Diffraction Method. The catalyst developed on PtNPs/BNQDs/ILs has proven to be costeffective. Moreover, the PtNPs/BNQDs/ILs nanocomposite has achieved a higher peak for the current oxidation of methanol, when compared to BNQDs/ILs and ILs. Therefore, this catalyst has a better catalytic activity.
