This Special Issue compiles a set of innovative developments on the use of graphene-based materials in the fabrication of sensors. In particular, these contributions report original studies on a wide variety of sensors, such as gas sensors for NO2 or NH3 detection, antibody biosensors or mass sensors. All these devices have one point in common: they have been built using graphene-based materials like graphene, graphene oxide, reduced graphene oxide, inkject printing graphene, graphene-based composite sponges, graphene screen-printed electrodes or graphene quantum dots.

Graphene oxide can be used as a precursor to graphene, but the quality of graphene flakes is highly heterogeneous. Scanning Raman microscopy (SRM) is used to characterize films of graphene derived from flakes of graphene oxide with an almost intact carbon framework (ai-GO). The defect density of these flakes is visualized in detail by analyzing the intensity and full width at half-maximum of the most pronounced Raman peaks. In addition, we superimpose the SRM results with AFM images and correlate the spectroscopic results with the morphology. Furthermore, we use the SRM technique to display the amount of defects in a film of graphene. Thus, an area of 250 × 250 μm2 of graphene is probed with a step-size increment of 1 μm. We are able to visualize the position of graphene flakes, edges and the substrate. Finally, we alter parameters of measurement to analyze the quality of graphene in a fast and reliable way. The described method can be used to probe and visualize the quality of graphene films.

Graphene’s unique mechanical, thermal and electrical properties make it an important material for research consideration. Additionally, the covalently bonded carbon atoms in graphene have potential applications in future technologies. Different methods have been proposed to synthesize graphene, but chemical vapor deposition (CVD) is the most promising. Chemical vapor deposition is recognized as low cost and is the most economical method. In this research, the growth of graphene on exfoliated graphene by a chemical vapor deposition method on SiO2 substrates has been shown as having a good potential to produce vertical stacking of graphene layers on top of exfoliated graphene seeds’ flakes. This research will demonstrate experimental procedures, analytical techniques and supportive evidence to achieve vertical stacking of graphene-grown layers, on top of flakes after using chemical vapor deposition.

Graphene sheets was a fascinating material with its tantalizing applied foreground.A prerequisite for exploiting most proposed applications for graphene was to seek for a method that readily and simply produced graphene sheets in large quantities.By far,graphene sheets can be prepared by three techniques in general.Among them,oxidation and reduction processing graphene sheets was the most suitable for producing graphene sheets in large quantity.XRD,transmission electron microscopy and FT-IR spectra analysis indicated that graphene single sheets were readily synthesized through the chemical processing.Moreover,the crystal structure of the graphene nanosheets was maintained intact after chemical functionalisation.

The authors investigated the influence of substrates on Raman scattering spectrum from graphene. The room-temperature Raman signatures from graphene layers on GaAs, sapphire, and glass substrates were compared with those from graphene on the standard Si∕SiO2 (300nm) substrate, which served as a reference. It was found that while G peak of graphene on Si∕SiO2 and GaAs is positioned at 1580cm−1, it is downshifted by ∼5cm−1 for graphene on sapphire and, in some cases, splits into doublets for graphene on glass with the central frequency around 1580cm−1. The obtained results are important for nanometrology of graphene and graphene-based devices.

He notes that, since graphene's discovery, scientists working with natural graphite to produce graphene have used what is known as the Hummers method to turn graphene oxide into reduced graphene oxide (or rGO - a term which [Gordon Chiu] says has been incorrectly and interchangeably used with the term'graphene').
Because graphite has the same composition and arrangement as graphene, natural graphite is a popular and cost-effective precursor in the production of many graphene materials, including graphene nanoplatelets, reduced graphene and graphene oxide, Dr Elena Polakova, CEO of Graphene Laboratories told IM.
In order to restore some of graphene's natural properties - because graphene oxide is not conductive like graphene - we reduced the samples to create reduced graphene oxide. We then went a step further and converted the reduced graphene oxide into a paste with applications in conductive inks and coatings.
