“…The interest in graphene research from 2004 has increased exponentially. Several reviews about graphene have been published all with a different focus [15,27,[30][31][32][33][34][35]. In this review, rather, we shall consider a panoramic approach of the synthesis methods of graphene (particularly from graphite), and some properties and application in polymer composites.…”

Graphene is a new and exciting material that has attracted much attention in the last decade and is being extensively explored because of its properties, which have been described with so many superlatives. Production of graphene for large scale application is still a major challenge. Top-down graphene exfoliation methods from graphite, such as liquid-phase exfoliation which is promising because of low cost and high scalability potential will be briefly discussed. We also analyze the challenges and possibilities of using graphene as a nanofiller in polymer composites which has resulted in enhanced electrical, mechanical and thermal properties. In this review, we take a panoramic approach to give insight on the different aspects of graphene such as properties, graphite-based production methods and also examples of graphene application in polymer composites and will be beneficial to both novice and experts.

“…Otherwise, the strong van der Waals interactions among the reduced graphene sheets results in their rapid aggregation in solution during the chemically reduction process. Then, water soluble GNPs-GR can be successfully obtained by the non-covalent interaction of graphene with sodium dodecylsulphate (SDS) in this procedure [26,27]. Further, we also demonstrate the direct electrochemistry and electrocatalysis of hemoglobin (Hb) immobilized in GNPs-GR-SDS films for the detection of NO.…”

A simple two-step method was employed for preparing nano-sized gold nanoparticles-graphene composite to construct a GNPs-GR-SDS modified electrode. Hemoglobin (Hb) was successfully immobilized on the surface of a basal plane graphite (BPG) electrode through a simple dropping technique. Direct electrochemistry and electrocatalysis of the hemoglobin-modified electrode was investigated. The as-prepared composites showed an obvious promotion of the direct electro-transfer between hemoglobin and the electrode. A couple of well-defined and quasi-reversible Hb CV peaks can be observed in a phosphate buffer solution (pH 7.0). The separation of anodic and cathodic peak potentials is 81 mV, indicating a fast electron transfer reaction. The experimental results also clarified that the immobilized Hb retained its biological activity for the catalysis toward NO. The biosensor showed high sensitivity and fast response upon the addition of NO, under the conditions of pH 7.0, potential -0.82 V. The time to reach the stable-state current was less than 3 s, and the linear response range of NO was 0.72-7.92 μM, with a correlation coefficient of 0.9991.

“…Architecturally, graphene, a monolayer of tightly packed carbon atoms (Geim and Novoselov 2007;Wang et al 2014), possesses multiple attachment sites (Kakran and Li 2012;Kim and Kim 2012) and tremendous surface area (Qin et al 2014) also portrays vital podium to conspicuous molecular interaction with microorganism (Shen et al 2012;Zou et al 2016). Exceptionally immense surface to volume scale (Sur 2012;Drieschner et al 2016;Qian et al 2014) and smaller dimension than cells and cellular organelles (Zhang et al 2016;Snitka 2015) expedite graphene to permeate into basic biological structures (Cherian and Mohanan 2014;McCallion et al 2016) and disruption of cell functions of microorganisms (Roda et al 2014;Liu et al 2011a). The enormous loading of the bioactive agent onto the surface of graphene sheets (Akhavan and Ghaderi 2010;Liu et al 2011b) tailors promising nanoplatforms for designing antimicrobial dosage formulations.…”

Tolnaftate–graphene composite-loaded nanoengineered electrospun scaffolds as efficient therapeutic dressing material for regimen of dermatomycosis

Graphene "The novel carbon nano-trope" tailors auspicious platform for designing antimicrobial regimen by virtue of its conspicuous molecular interaction with the microorganism. In this work, Tolnaftate (Tf), an antifungal drug, was mingled with Graphene nanoplatelets (Gn) to develop composite (Tf-Gn) via the wet chemical route, embedded in a biocompatible polymeric blend of Eudragit RL100/Eudragit RS100 (EuRL100/EuRS100) and subjected to electrospinning to obtain nonwoven nanoengineered scaffolds (nanofibers) for enhanced anti-dermatophytic virtue. Pursuing cluster of optimization experiments, 20% w/v EuRL100/EuRS 100 was found to be adequate for formation of smooth, defect-free, and regular fibers. Field emission electron microscopy (FESEM) acknowledged zestfully fabrication of smooth, shiny, nano-range, and mesh-like architecture, comprising distinct pockets within their structure. Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimeter (DSC) conceded formation of the composite Tf-Gn, its physical compatibility with polymers, and improved thermal behavior. Exceptional swelling capacity, significant hydrophilicity, and immense drug entrapment efficiency were obtained of nanofibers fabricated from 3:1 ratio of EuRL100/EuRS100 polymers blend owing to relatively higher permeability which gratified essential benchmark for fabrication of nanofibrous scaffold to alleviate fungal infections caused by dermatophytes. In vitro drug release interpreted controlled liberation of Tf in dissolution media, following Korsmeyer-Peppas model kinetics, and suggested a diffusion-based mechanism. Microdilution broth method was performed for in vitro antifungal efficacy against extremely devastating dermatophytes, i.e., anthropophilic Trichophyton rubrum and zoophilic Microsporum canis, exhibited preeminent growth inhibition against T.rubrum and scanty for M.canis. Findings revealed the superior antifungal activity of Tf-Gn-loaded nanofibers as compared to Tf-loaded nanofibers and recommended potential dressing materials for an effective regimen of dermatomycosis.
