“…A sharp peak at 2h = 26.6°was noted. Graphene oxide has a peak centered on 2h = 10.4°and graphene peak is centered around 2h = 24°-26° Wang et al 2009;Mondal et al 2012;Li et al 2012). This is attributed to the (002) crystal plane (Li et al 2012).…”

Graphene nanosheets were produced after synthesizing graphene oxide via Hummer's method and a modified Hummer's method. The obtained graphene after reduction was dispersed in 1-propanol to get a coating solution. Mild steel coupons were coated with the graphene solution via dip coating method. Corrosion studies were carried out at different environments like water (pH 6.0), HCl (0.1 N), NaCl (3.5 wt%) and NaOH (1 M). Tafel analysis showed a reduction in the corrosion rate up to 99 % after three layer deposition with the graphene developed using the modified Hummer's method. X-ray diffraction and Raman Spectroscopy confirmed the presence of graphene.

“…Derivatives of graphene, including GO, artificially reduce GO (rGO) [66], and doped graphene [66] has been studied to know its universal implementations in biodetecting and biosensing for biomolecules such as thrombin [67], oligonucleotides [68], ATP [46], amino corrosives [69] and dopamine [70]. Nowadays, various biosensors-based GO have been produced, such as: (1) utilization of fluorescence quenching capacity of graphene which is supereffective and few FRET-based biosensors have been created [50,67]; (2) FRET-based biosensors of graphene have been created on the basis of their electric property [71].…”

“…This can be ascribed to the high electrode surface area and the inherent unique character of the graphene structure, distinctive of the CF. 31 It has been reported that the surface of CFM can be activated by electrolytic oxidation and the formed amorphous surface can improve electrode kinetics. 27 Here, the voltammetric behaviors of CFM, before and after electrolytic treatment in the electrolyzing solution used for the preparation of G-CFM containing everything except the graphene oxide, were carried out in the solution containing 0.5 mM DA and 0.1 M pH 7.0 PBS.…”

Graphene, as a novel carbon nanomaterial, exhibits superior performance in electrochemical sensors. Here, graphene was applied to the microelectrode system by a simple method. A novel graphene coating carbon fiber microelectrode (G-CFM) was fabricated by electrodepositing graphene on the surface of carbon fiber. The fabrication method is fast and simple. Scanning electron microscopy and Raman spectroscopy demonstrated that carbon fiber was successfully modified by graphene. The electrochemical behavior of G-CFM was characterized by potassium ferricyanide and dopamine (DA). The electrode exhibited much larger current response and less overpotential response, compared to CFM. The microsensor for DA showed good sensitivity and selectivity, and the electrode had good stability. It is believable that the unique characteristic of graphene holds promise for the advanced microelectrode system for highly sensitive detection of various targets.
